Preamp recommendations, surround
I would like to upgrade my audio-HT system with a pre-processor (or
multi-channel receiver with line-level outputs) that could replace several components I'm now using. These include DVD players, turntable, a Carver C-1 stereo preamp feeding power amps for stereo; an Onkyo DS676 receiver with preamp sections used with interconnects feeding five external power amps for DVD audio, Dish TV, and (in "pass-through mode") as a multi-channel preamp for mutli-channel SACD audio. For SACD multi-channel, I also sometimes use an Outlaw ICBM for bass management. I'm using several Magneplaner speakers, including 3.6r's in the front, and two Velodyne woofers. I know this all sounds confusing, but it works somehow. However, it would be helpful if I could replace all these components (and interconnects) with a new and improved, integrated multi-channel processor with current digital output capabilities. Here's what I think I need: A. Multi-channel pre-amp/processor including preamp sections for stereo and multi-channel, with low distortion equivalent to the audio response I get (in stereo) from the Carver preamp; B. The multi-channel preamp having capability for either pass-through or processing mode for SACD, the processing mode providing bass management at least equivalent to what the Outlaw ICBM provides (including X-overs that are individually adjustable for front, mid, and surround, speakers) and preferably with processing in both analog and digital modes; C. Multiple switchable video inputs and outputs, including HDMI output(s) compatible with current and future 1080p DVD and Dish programming; and D. Capability of handling the audio output modes now used or proposed for use with HD DVD, including HDMI 1.3 surround sound and "true HD". (For example, I don't want to invest $$$$ in a pre/processor in 2006 and then find that it isn't designed to handle surround sound formats used with BlueRay HD DVD in 2007.) I prefer the keep the cost below $1,500 - $2,000, and I'm willing to wait until next year if that's necessary. My question is: are these functions available now in a single pre/processor, or, if not, is it likely that they will be available next year? Or, is it expected that they won't be available in a single unit? In other words, practically speaking, would it be more reasonable to use separate components for audio and video? (For example, as outlined above, I'm now using separate preamps for stereo and surround, and I think that my old Carver preamp provides better audio than the Onkio receiver, despite the fact that it is newer and can perform the same function in stereo. - I don't want to give up this audio performance.) Another question is: The new surround receivers seem to have more up-to-date video functions. - Would they provide the same quality audio and the same versatility as a pre/processor? For example, as understood, the Outlaw 990 processor (more expensive than their 1070 7.1 receiver) doesn't include some of the features of the 1070 unit, such as bass management in the analog mode. (One of my problems is that the people talking about new HTMI connections don't seem to know anything about audio and bass management, etc., and vice versa. Corrections, suggestions, and advice will be appreciated. Jim |

IMHO this is an unrealistic expectation because HDMI and the hi-res DVD formats are moving targets. As for SACD bass management in a multi-channel pre-amp, I'm not aware of any in the $1,500 to $2,000 price range you note. Talk to any honest home installer and most will tell you they are NOT using HDMI to link their customers systems because HDMI 1.0 doesn't always talk to HDMI 1.1 and the same issues pop up with HDMI 1.2. And now we're supposed to get HDMI 1.3 and no one really knows how it will handle HDMI 1.0, 1.1 and 1.2 data. And every manufacturer's versions of their HDMI is a little bit different from another manufacturer so this just compounds the problems with the various components seamlessly passing data. IMHO, anyone who wants to hook up all their equipment right now via HDMI is nothing more than a "beta" tester for the home entertainment industry. YMMV, of course. Most installers I know wire their customer's systems using the component inputs on their video displays because they have so many problems getting different brands with the same HDMI numbers to "talk" to each other. The only problem is that the content providers can "flag" their hi-rez DVDs to either downscale or not pass any data at all to the component output of a hi-rez DVD player, but so far, none have said they will do this. But do you really trust Hollywierd? I would counsel caution and conservatism when it comes to hi-rez DVDs and HDMI: HD-DVD and Blu Ray could well end up fizzling like SACD and DVD-Audio and I don't think knowledgeable consumers really trust the content providers to NOT turn on the flag to either block or down-rez the output to the component video output if a hi-rez DVD format actually becomes successful. Many DVD players will upscale a DVD to 720p and unless you've got a 42" or bigger screen I don't think you're going to see much difference between upscaled 720p and native 1080p from a hi-rez DVD player on a screen this size. As for the pre-amp, I personally like the control flexibility of the Yamaha RX-V series, so I bought one of their receivers to use solely as a pre-amp and I can feed and switch component video from my DISH Network system and DVD player to my video display. The Yamaha was a heck of a lot cheaper than one of those über-expensive pre-amps that do HDMI switching and multi-channel bass management and may be obsolete in 2 or 3 years. IMHO, the pre-amps of many A/V receivers are far more advanced and more sophisticated than the A/V pre-amps from the specialty high-end manufacturers who probably have to contract out the A/V engineering for their units because they can't afford to keep a really good A/V design engineer on staff. Again, YMMV, of course.

Thanks for your response. - I'm still a little confused, as indicated below.

Most installers I know wire their customer's systems using the component inputs on their video displays because they have so many problems getting different brands with the same HDMI numbers to "talk" to each other.

I'm not sure I understand the significance of the blocking/down-rez flag. - If I understand the concept, they can turn the flag on to degrade the component video output, but not the HDMI output. If so, wouldn't it be safer to have both the component and HDMI options? Many DVD players will upscale a DVD to 720p and unless you've got a 42" or bigger screen I don't think you're going to see much difference between upscaled 720p and native 1080p from a hi-rez DVD player on a screen this size. Actually, I have a 92" screen (front projection), and the image I get from high definition broadcasts (via DISH) is far better than STV and normal DVD images. I haven't tried an upscaling DVD player however. As for the pre-amp, I personally like the control flexibility of the Yamaha RX-V series, so I bought one of their receivers to use solely as a pre-amp and I can feed and switch component video from my DISH Network system and DVD player to my video display.

Again, YMMV, of course. In any event, I'm beginning to agree that it may be impractical to expect one pre/processor to handle both functions (video and audio) well, so I'm prepared to wait until things settle down re HDMI. Meanwhile, for audio, I am not satisfied with the multi-channel SACD sound. I'm presently using the preamp section of an Onkyo DS676 receiver (with external power amps) and a Sony CE775 multi-channel SACD player. (For stereo, however, I don't use these components but instead use an old Carver preamp and a Sony S9000ES (CD/SACD stereo) player.) As in your case with the Yamaha receiver, I use the Onkyo for volume control and for handling signals from a DISH satellite, although I also have an external switching arrangement also for switching video sources. As mentioned, the audio response in stereo, using the Carver preamp and 9000ES player, is great. However, IMO the audio from multi-channel SACDs sounds like the high frequencies have been somewhat attenuated or rolled off. So, I'm concluding that at least one of the components used for SACD multi-channel - i.e., the CE775 player and the Onkyo receiver - isn't performing as it should. Also, because I only have two full-range speakers (Maggie 3.6R), I think I need some form of bass control, although I have tried it with all controls switched to "pass-through." Does anyone have suggestions for improving the multi-channel SACD audio other than replacing everything with high-end, high-$$$ components? I'm guessing that upgrading the multi-channel SACD player may be a good first step, since I have read other reviews questioning the response of the CE775. Jim |

It is brighter and it is more transparent. Unfortunately, it sounds a little "rougher" in the midrange than the other two, but for me with multichannel, its an acceptable trade off. They are out of production, but there is an outfit on eBay that consistently offers grey market Canadian units for just under $300...and at that price they are an absolute steal. If I were you, I'd give one of them a try as your first option. |

Also, because I only have two full-range speakers (Maggie 3.6R), I think I need some form of bass control, although I have tried it with all controls switched to "pass-through." Does anyone have suggestions for improving the multi-channel SACD audio other than replacing everything with high-end, high-$$$ components? I'm guessing that upgrading the multi-channel SACD player may be a good first step, since I have read other reviews questioning the response of the CE775. Jim, I own the Sony CE775, the Sony C222ES, and the Sony C2000ES CD/SACD players. Of these, the C2000ES is the latest, and it sounds substantially different than the other two. It is brighter and it is more transparent. Unfortunately, it sounds a little "rougher" in the midrange than the other two, but for me with multichannel, its an acceptable trade off. They are out of production, but there is an outfit on eBay that consistently offers grey market Canadian units for just under $300...and at that price they are an absolute steal. If I were you, I'd give one of them a try as your first option. Thanks for the suggestion. - Did you also think the high frequency response of your CE775 was attenuated or rolled off? Not per se, Jim. But both the CE775 and the C222ES have a "dark" sound that I always considered a "house sound" of Sony going back to their CD units of the late '80's, until I experienced the C2000ES. Whatever caused this "dark" sound also obscured some detail in the upper frequencies...in other words, it is harder to "listen into" the sound, which causes them to sound duller. |

It converts SACD to PCM whether it's multichannel or stereo. Wel, what I meant is that I understand (from the Audioholics note) that the Oppo has two settings for HDMI audio: 'Multichannel' and 'SPDIF', and for SACD, it always sets itself to 'Multichannel' (there is no output when set to SPDIF). 'Multichannel' applies DSP, so SACD will certainly be converted to PCM first as in all other consumer devices that apply any DSP to SACD beyond bass management (mu understanding is that Denon devices, at least, do BM in the DSD domain). I suppose one could set the DSP parameters to be a neutral as possible (eg., no delay, no BM, no gain or boost) in hopes of altering the DSD--PCM signal as little as possible before it goes to the AVR (where extensive DSP could be applied). I have an Oppo 97HD sitting a a box still packed next to me, i hope to get around to trying its HDMI audio funtions out this weekend with a Pioneer AVR. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.

In the Oppo, it is converted regardless of what you choose, so why is it an issue? Kal |

The conversion from DSD to PCM requires DSP. It's how things get done in digital audio. Not disputing that. The point is there does't seem to be a way to get the Oppo to output DSD natively to an AVR that can decode it. .. as in all other consumer devices that apply any DSP to SACD beyond bass management (mu understanding is that Denon devices, at least, do BM in the DSD domain). Nope. Time delay, but not BM. You sure about that? AIUI, time alignment requires DSD--PCM, in the Denons and elsewhere. I suppose one could set the DSP parameters to be a neutral as possible (eg., no delay, no BM, no gain or boost) in hopes of altering the DSD--PCM signal as little as possible before it goes to the AVR (where extensive DSP could be applied). In the Oppo, it is converted regardless of what you choose, so why is it an issue? My piont was it needn't be, but apparently it is, if the review at audioholics is to be believed. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.
