Pro Amp suggestions for subs and ribbons
Hi,
I wanted to borrow some of your knowledge/experience. I'm looking at some proamp options for a multiamped hometheater system. One of the amps I will require is for a set of 72" ribbons that measure cleanly at 6 ohms; i.e. no dips, basically a resistive load. Accordingly in this area I'm looking for an amp that is very clean in frequency response and stable down to 4 ohms. One amp I'm looking at (because it can be had cheap) is a Samson F1200. It can be found really cheap in the used market, it is rated to down to 4 ohms and will produce 400/ch at 8 ohms (about the power range I'm looking for). Now, even though I'm looking for cheap, this should not be construed as my not being willing to pay what is required for a good amp. I just do not feel the need to pay _more_ than more needs require in this area. Now the ribbon is crossed over to a line array of Seas drivers at 225 Hz, so needless to state the amp will be dealing with most of the midrange and all of the treble. I will not sacrifice these areas for the sake of saving money, but then again, I don't intend to throw money away ;-) As a side note, I had not visited rao in a long time, did not realize what wasteland it had become. Some of the reactions make Zip (may he rest in peace, just found out) seem like he was a master diplomat. Thanks |

The gotcha with ribbons is usually the need for lots of power. They are a relatively inefficient lot it is hard to get lots of turns in a strong magnetic field with a ribbon design.

I will not sacrifice these areas for the sake of saving money, but then again, I don't intend to throw money away. Try eBay. USA 850s and 900s are the most common "find", usually closing around $200. Will 375 wpc or so do the job for you? How much does it take to damage that ribbon? It would be good to not be able to go there. |

Pro Amp suggestions for subs and ribbons
Is a pretty large ribbon and if I remember correctly it is rated up to
400 watts. You are right about it being an easy load, if I remember the graphs correctly it never droped below 6 ohms and had an easy phase. It was virtually a resistive load. This is why I was thinking I might get away with a proamp that was not necessarily a top proamp. That being said, I'm not going through all the trouble of working on my hometheater to use an amp that is going to be suboptimum. Price is not an issue, but being practical, I don't like throwing away money on audio jewelry. Quality and reliability are what matters. The one thing that concerns me about pro amps is fans though.

He used a resistor to slow the fan down, as the heating during audiophile use is only a tiny fraction of the worst that the amp is normally prepared to handle. Sound quality is excellent. The owner has a similar approach to yours. He's got the money to spend, but he doesn't want to spend it foolishly. |

Last time I heard a pro amp doing a credible job of driving ribbons, it was
a QSC USA 1300. What about your beloved Mackies or the new Behringer amps. If the Mackies are good candidates I could place a resistor in series with the fan to slow it down and reduce the noise. The Behringers I understand may be copies of the QSC and could be had for $300. Try eBay. USA 850s and 900s are the most common "find", usually closing around $200. Will 375 wpc or so do the job for you? How much does it take to damage that ribbon? It would be good to not be able to go there. I think 375 he should be perfect. I would never listen to it that loud, but it would have more than sufficient headroom for peaks and the ribbons should easily handle it. BTW, I seem to remember reading some negative stuff on the 900s, but I'm not sure. Thanks for all your insights. BTW, years ago we had a couple of discussions in RAO about blind tests and I was not in total agreement with your total dismisal of sighted tests. Even though I still don't totally agree (I think they sometimes can be used to determine if further investigation is warranted), I can now see why you were so fervently against it. For many sighted testing is the measure, especially in RAO and some magazines I no longer subscribe to (could not take it any longer). What is really dissapointing though is the level RAO has droped to. It caught me totally by surprised how my inquires were used as another excuse to debase any form of discussion. Regards, Goyo |

a QSC USA 1300. What about your beloved Mackies or the new Behringer amps. If the Mackies are good candidates I could place a resistor in series with the fan to slow it down and reduce the noise. The Behringers I understand may be copies of the QSC and could be had for $300. Try eBay. USA 850s and 900s are the most common "find", usually closing around $200. Will 375 wpc or so do the job for you? How much does it take to damage that ribbon? It would be good to not be able to go there. I think 375 he should be perfect. I would never listen to it that loud, but it would have more than sufficient headroom for peaks and the ribbons should easily handle it. BTW, I seem to remember reading some negative stuff on the 900s, but I'm not sure. Thanks for all your insights. BTW, years ago we had a couple of discussions in RAO about blind tests and I was not in total agreement with your total dismisal of sighted tests. Even though I still don't totally agree (I think they sometimes can be used to determine if further investigation is warranted), I can now see why you were so fervently against it. For many sighted testing is the measure, especially in RAO and some magazines I no longer subscribe to (could not take it any longer). What is really dissapointing though is the level RAO has droped to. It caught me totally by surprised how my inquires were used as another excuse to debase any form of discussion. Regards, Goyo |

Your comment about the group being a lot more civilized in the days of Zippy are regrettably quite true. The irony is that some of these creeps were friends of Zippy. |

Pro Amp suggestions for subs and ribbons
Thanks Tom. I have been trying to get a handle on them. I was
troubled by their lack of 2 ohm rating, and their tech support (at least the couple of people I have spoken with) do not seem to have much background as techs. But some of their data looked good and the guys at SVS subwoofers seemed to like them (at least the model you use). Thus my interest on the F1200. According to Samson it is sonically identical to the S1000 (i.e. that have not crippled it in any way), the former has greater bandwith (its rated to 50Khz as opposed to 20Khz) and power, but the latter has nicer features and higher damping factor. The differences not withstanding, I think I may be correct in assuming the greater bandwith and lesser damping factor should have no sonic effect. So it all boils down to is it the same quality as the S1000, and herein lies my dilema. The people telling me yes are the same techs I found wanting in other areas "Arny Krueger" What about your beloved Mackies or the new Behringer amps. Another friend of mine who builds his own ribbons has a Macie M1400. Sounds like a good start (no pun intended) That can work, although the base fan noise seems higher on the Mackies than on the QSCs. The Mackie puts the fan at the base of a horn that is pointed right out the front of the amp. I see, that is why you always mention the fan noise. From your experience with your own 1200, would a resistor slow it down enough to mitigate the noise, or do you feel it will always be a potential factor (especially in quiet scenes/music moments)? The Behringers I understand may be copies of the QSC and could be had for $300. I've heard people say nice things about them, but I don't know anybody who has one. Try eBay. USA 850s and 900s are the most common "find", usually closing around $200. Will 375 wpc or so do the job for you? How much does it take to damage that ribbon?

BTW, I seem to remember reading some negative stuff on the 900s, but I'm not sure. People like to **** on em because they do a lot of humble work. They are clean and they last. That is good to know, the more options I have the better off I'll be. Believe it or not, one stated goal of this running crapmouth act on RAO is to get me to stay away. The good news is that there are a goodly number of other audio groups. Your comment about the group being a lot more civilized in the days of Zippy are regrettably quite true. The irony is that some of these creeps were friends of Zippy. I did not care much for Zip's reactions in the later years (I found in his early years he could be a pain, but he also seemed to have more to contribute), and I think that may have been part of the reason I moved to other forums (e.g. Basslist), but now the area has become a virtual wasteland engaged primarily on adhominems and reproduction of the same story time and time again. It is sad to see, but I guess it is also to be expected considering the medium. Again, thanks Arny and thanks Tom (love your work on subs, especially the article dealing with your DIY basement sub).
