Specific Pre-Amp advice darkstar1 As you correctly said your dual 4 is 100kohm input impedance, which makes it a perfect match with the Schiit Freya in all modes.As not only does it have a great impedance match, but if you look in your user manual you'll see it only n... | |
More discrete R2R Mulibit dacs. plutosThis is a bit off topic, I don’t know how this works in the US, but in Australia I have a 55" Panasonic plasma (I don’t find led or o’led natural), and a Panasonic PVR. On one or the other can’t remember, in the setup menu both or one of the... | |
Accuphase DP75V: does it still hold its own ? I don't understand why your so keen to get out of the CDX2 + XP5XS DP85 Vintage 2002AD1853 "Delta Sigma"Laser KHM230AAA cheap build quality compared to all the others.http://www.ebay.com.au/itm/Used-Good-Original-Sony-KHM-230AAA-Laser-Head-E-R... | |
Accuphase DP75V: does it still hold its own ? I’m not sure that so many people bought that optional board I would say if the new buyers had the deep pockets to buy one new, they would have got the board to do sacd with also.But watch if your thinking about the transport for that laser with t... | |
Specific Pre-Amp advice darkstar1 I will look into the Freya. It does not say its OTL but I will research it. No it won’t be OTL (output transformerless) you can see that in the attached circuit pic. But I’m sure it will be OCC (output capacitor coupled) the 4 big fat ... | |
More discrete R2R Mulibit dacs. Wish I had the funds.Cheers George | |
More discrete R2R Mulibit dacs. bigkidz If you care to look/study and compare most dac chip manufacturer data sheets are adhered to for implementation, even some (hiend ones) using even the exact I/V stage and buffer stage that’s on those data sheets. "Some" (me, Audio Note abo... | |
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... | |
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... | |
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... |
