2005年2月20日 · I'm interested to find a really good source with PCM63. The Monarchy M24 Tube Dac uses this chip... and is simply outstanding! Sounds great with all my phones, especially the Senn HD580/600s and HD650s.

2006年3月22日 · Just curious if anyone knows of any high-end units using the PCM63. Here's a few I'm aware of: ACCUPHASE DP90 AUDIO NOTE DAC-3 WADIA 15 I'm curious which of the above run in filterless mode as well as any other details on the circuits. Thanks!

2017年5月12日 · And make no mistake, there's a reason the TDA1541A has that sort of legendary status, along with the PCM63, AD1862, and UltraAnalog chips/modules. Interestingly, the Model S reminds me the most of the current, multibit Schiit DACs out of all these on the list in terms of overall tone, timbre, and background.

2015年8月13日 · No company can match more accurate than a 20-bit resistor ladder, so the highest performance true R-2R DAC chips are the 20-bit ones, such as the PCM63 and AD1862. The PCM1704 is a hybrid of two resistor ladders, a MSB and LSB ladder, with an algorithm that combines the sum of the LSB ladder at a fraction of the output voltage to the MSB ladder.

2016年2月13日 · Highly aclaimed Abbas Audio (from the Ukraine) offers a DAC built around the PCM63 chip. In an English language article the guy behind Abbas Audio discloses his chip preference: "My favorite chips are all the chips I use to build digital-to-analog converters: PCM56, PCM58, PCM63, TDA1543, TDA1541, TDA1540

2019年12月12日 · PCM63 is a higher performing chip compared to PCM56, lower distortion and noise, higher theoretical bit depth as well - it is a 20-bit chip vs 16-bit for the PCM56. Both use Sowter step up transformer I/V conversion, however the PCM56 DAC uses a tube voltage gain stage on its output, CCS loaded and capacitor coupled, as such the Sowter I/V ...

2008年5月9日 · This DAC is by far the best design in the DIY world that I have seen. You have the best digital filter ever made (PMD100), arguably the best DAC chip (PCM63-KY) and without a doubt one of the best analog stages. I recieved my board and now understand why this isn't a popular build. The PCB is so crammed with parts its near impossible to decipher.

2015年8月13日 · Recently acquired a good condition and recently serviced (recapped) Theta DS Pro Gen III DAC and have been enjoying it quite a bit with the Audiophilleo 2. I had been on the lookout for a PCM63 based Theta after a lot of research, and when the Gen III popped up, surprisingly in the little town I live, I just had to give it a try.

2004年11月28日 · They are prototype PCBs for the discrete I/V converter board I designed, to be used with current output DACs, especially of the multibit variety (PCM63, PCM1702, PCM1704, AD1862, TDA1541, ect). I currently own two DACs, an Audio Alchemy DDE v3.0 (PMD100 digital filter, dual AD1862N-J DACs) and an Adcom GDA-600 (DF1700 digital filter, dual PCM63 ...

2006年6月9日 · I find the PCM63 sounds a bit more musical, but both the PCM63 and PCM1704 are quite a bit more linear than the TDA series. Because of their lack of linearity, the TDAs really don't achieve 16 bit resolution in practice, and 16 bits is alreally pushing it to recreate the musical picture without massive sampling rates.
