So far I've gained more enjoyment from the tube amps -- but ones that are very resolving, not just "warm". I forgot to mention the WA8, which was a lovely pairing, if not as detailed as my main system. That amp is exactly the right kind of "warm" and is simply highly enjoyable to listen with. For whomever asked, I have a Black Dragon. I'd forgotten about it. When I last visited Drew he asked what I had and he handed me a bunch of cables to try. The times I've tried the...

Back in 2012, I bought a Metrum Octave and I thought I'd see for myself how a non-oversampling DAC performs. These are only sine waves at various frequencies through the Reference 7 and Metrum, They are quite interesting. Note that the scale is not always exactly the same. Reference 7, 1 kHz 44.1/16 (Distortion is probably noise in the scope) Metrum Octave, 1 kHz 44.1/16 Reference 7, 5 khz 44.1/16 Metrum Octave, 5 kHz 44.1/16 Reference 7,...

The only time to care about the difference is if you're using a device that can only read one, not the other. Some Chinese players can only read hi-res files if they are in FLAC format.

I have quite a bit of DSD the quality of which I don't find to be that good. A lot of it would have started as PCM in the first place anyway, and if that wasn't well recorded and mastered, then there is no possible benefit IMO.

I've had various NOS DACs here, and they all sounded clearer when they were fed high-res or iZotope was used to up-sample before sending the data to the DAC. I've measured the distortion of NOS DACs, and it is within the audible band. I used to believe as you do about impulse responses, but after researching sufficiently I now understand why it is wrong. DSD may have a high sampling rate, but it is only 1-bit. For various reasons, it is technically worse than PCM. What is...

It's the other way around. A square wave is the sum of multiple harmonics. A DSD "impulse" isn't in music either. Multiple harmonics do not sum together in music to form anything like a square wave, unless the music is clipping, which is a different issue. I think the issue you may be closest to is that of aliasing close to the Nyquist frequency, which is a filter issue. Anyhow, whether or not a DAC can accept DSD 512 is kind of crazy IMO. There is effectively no music of...

The "ringing" you only see, as you are only supposed to, next to impulse responses and square waves, which do not exist in music. The whole thing about DACs sounding "digital" being caused by ringing very much appears to be completely false, but from my experience some of it does appear to be the result of poor filter design and component noise, as well as timing errors in SD DACs.
