| Impedance matching device energeezer Could could go for what I suggested here, it has all the active flavours, all with low output impedance's.https://forum.audiogon.com/discussions/specific-pre-amp-advice Cheers George | |
| Specific Pre-Amp advice I would opt for a straight passive preamp seeing your amp has 100kohm input impedance, a perfect match.But you could: Try the Schiit Audio Freya, as it can be a passive pre, active tube pre, or active solid state pre. So you can suit your mods. Al... | |
| Impedance matching device energeezer Assuming you have an impedance mismatch between your pre and power amp is there a device which will correct or compensate for this? There are no set rules: I say with all the listening/measurements I’ve done if the output impedance of ... | |
| Accuphase DP75V: does it still hold its own ? DP75V dose not read SACD It’s dac input will of the 75V if you have a transport that gives a SACD digital stream, and because of this it should do dsd as well. Certain model Playstation can give out SACD and the Stereophile review of the 75V says... | |
| SE vs Balanced volume Like I said the only time balanced is an advantage is for noise rejection, but is only an advantage over rca with very long interconnects, and there is no sound advantage, if anything it’s a worse sound in this fake balanced connection case above ... | |
| More discrete R2R Mulibit dacs. Yes the AD5791 is still available but it was never designed as an audio dac, I don’t know what the down sides are for this in audio use. I believe the last audio one was the PCM1704 and it was more like >$120, a Delta Sigma is like <$10. "AD... | |
| SE vs Balanced volume INA134 is a differential amp (instrumentation amp), designed for audio, that provides very high (90dB) Common Mode Noise Rejection. It’s still a faked balanced into what is obviously not balanced amp, and it’s also an unwanted opamp in the signal... | |
| More discrete R2R Mulibit dacs. kalaliSo, all those discrete components combined replace one chip? Yep, and they stopped making them years ago, because Delta Sigma was more than 20 x cheaper to make and allowed for dsd use, probably because there was no laser trimming to be ... | |
| Synergistic Red Fuse ... Paul McGowan of PS Audio has articles on their site that states since the fuse is the bottleneck of the entire .So are all the fine circuit board tracks that lead to and from the fuse and every thing else. why not rip them out too and turn them a... | |
| Accuphase DP75V: does it still hold its own ? DP75V is a neat step forward I believe that could stem from it's ability to be able to decode sacd which is dsd without the flag, but for Redbook, if that's what you want, then the 75 is the way to go, as Mojo music implies 75v would be "a neat... | |
| Accuphase DP75V: does it still hold its own ? Then as I hinted stay with your CDX2 + XP5XS Maybe this will convince you Daniel what’s best for PCM Redbook CD replay, from MoJo Music. And why now there is a big swing back to R2R Multibit, even if it has to be done discrete, because the chip ma... | |
| SE vs Balanced volume steakster Seeing this amp is fake balanced, I would just use the rca out of the preamp (just incase it's also fake output) into the rca in of the amp, for the best sound if your interconnects are <5mt.No advantage in using balanced out of th... | |
| More discrete R2R Mulibit dacs. Here are some direct links to this amazing looking circuitry.https://static.wixstatic.com/media/4b933e_1f4d615d52364f9eb3e891e34ed6487d~mv2.jpg/v1/fill/w_520,h_347,q_85,usm_0.66_1.00_0.01/4b933e_1f4d615d52364f9eb3e891e34ed6487d~mv2.jpg https://sta... | |
| SE vs Balanced volume steakster Here’s a photo of the innards behind the RCA & XLR inputs of the SS amp. XLR is on the left, RCA on the right, the yellow wires go to the external toggle switch. Why the different results? Thx. Without the circuit, that to me looks... | |
| Accuphase DP75V: does it still hold its own ? Thanks, George.could you please tell me about the sonic differences you noti ed when you compared dp75 to dp75v ? and maybe to cdx2 Never compared them, but one is Multibit (DP75) and the other is Delta Sigma (DP75V) With all players I've comp... |
