Oh Teacher?
Can I run this player thru a passive preamp into the power amp with specs
listed here?I assume the amp input signal for max output power of 1.6V will allow the players Audio output:Output level: 2 Vrms (1 kHz, 0 dB) . Am I understanding these terms correctly? *** Digital Playback Specs: Audio D/A converter =24bit / 192kHz Audio Systemigital audio format =DTS digital output, Dolby Digital output Surround sound effects= Advanced Virtual Surround Sound (V.S.S.) Response bandwidth= 4 - 44000 Hz Digital output sample rate= 48KHz, 96KHz Signal-to-noise ratio =115 dB Supported digital audio standards= MP3, WMA Total harmonic distortion= 0.0025 % Dynamic range= 102 dB Sound output mode =Stereo Audio output: Output level: 2 Vrms (1 kHz, 0 dB) ---------------------------------------------------- Amp specs: Output Power: 100 W per channel into 8 ½ 200 W per channel into 4 ½ (both at less than 1% THD) Frequency response @ -3 dB: 2 Hz to 200 kHz Slew rate: 250V/µS Input impedance: 100 k½ each phase Input signal for maximum output power: 1.6 V Output impedance: 0.4 ½ Power supply energy storage: 180 joules Gain: 25 dB Power consumption: 250 VA at idle 1000 VA maximum at full power and on another note, going by the Player specs alone how would you expect it to sound? |

I am hoping to learn from an objectivist standpoint how i might expect my subjective listening expereince to differ if i spent the thousand pluss on the Krell rather than a Hundred on a passive preamp for the DVD/CD player.If anyone cares to explain or point me to resources which can explain how what the Krell can do, at least from an objectiveist standpoint should deliver a more completely detailed,clear, coherent sound thus finallly justifying for me the substantial extra expense.I have not found a way do A/B the two devices yet but if i can understand how the two machinces handle the job of CD playback and how the more expensive one does it orders of magnitude better maybe i'll have more peace of mind when i make my decision. |

Oh Teacher?
I don't fully understand your setup, but you can certainly connect the line
level output or headphone output of your DVD player to any line-level input. |

They should sound the same. If there's any difference, it's likely that the Panasonic player will sound better, simply because it uses newer technology, including better DACs. You can certainly use a passive preamp between those units, I do this in my own system with devices which have similar characteristics to those you mention above. BTW, please note that *any* unit which is playing CDs has an output frequency response limited to less than 22kHz, and a dynamic range limited to 93dB. The specs you quote are not applicable to CD replay. Of course, there will be differences in pride of ownership, the Krell is a classy piece of very solid construction, but has very old technology by modern 'universal' player standards. -- Stewart Pinkerton | Music is Art - Audio is Engineering |
