Itīs really interesting how the sound changes as you get up or down the volume. I havenīt associated it to the SFS size however, but probably boleary is right. Hey, youīre really an expert in SFS and volume control and not only driving blue cars!.
By the way, take a look at the car, ok itīs not a blue car and I have not money enough to buy one, but a few laps on the track were not bad at all...
Peter, yes, NOS tube rolling, what else!

Ultimate Audio Playback / Your thoughts about the Sound Quality / Tube rolling without tubes

During 20 years I used valve (or tube) amplification until I was tired of tube rolling looking for the "perfect sound". Then I decided to live with the imperfection and to work less. So I took the solid state route, I went even further and got sticked to the class D amplification. Iīm happy with the sound, spend less money and now listen to more music than before, but...but the old tube sound, once in a while, knocks at my door. I found a way to open this door and let the tube sound come in. How? By changing the SFS values.
Based on bolearyīs settings, which for me and so far are the best settings Iīve ever tested, I tried different SFS values, from the minimum 350 to the maximum 430 - the latter was the value Peter used for the NOS1 (no USB).
The boleary setting with a SFS value of 350 in my system produces a sound that I would call "exact", what I mean is that it is a sound with no frills, great sound but a bit dry for my taste.
Increasing the SFS to the maximum of 430 (I could reach even 500 but thatīs too much of everything) the sound is a little dense, thick, it is like if you use something like a WE300B in combination with other sweet tubes, nice sound but too colored. Nothing against the 300B or other tubes in a well implemented amplifier, just as an example.
Going down in the SFS setting Iīve found that the best sound is around 7 to 10 points above the 350 boleary value. So, for example, with 360 I found a sound thatīs natural, well delineated with great soundstage and not at all aggressive.
All in all a great way to rolling tubes without tubes.

Thanks Joachim, I have a Technics SP10MKII from the times I owned a music bar, still have also a Thorens 160, but I sold my great TW and my phono preamp. I donīt have a big Lp collection, maybe around 500 that are worthwhile, some of them also in cd. That means that I donīt want to invest a big amount in hardware or software, what Iīm looking for is an acceptable way to transfer the vinyl to digital wav files at a reasonable cost. Christoffer, I found this that talks about the RIAA, itīs very cheap and even sell a TT, I donīt know about the quality, however: http://www.dak.com/reviews/tutorial_lp.cfmJuan

Ultimate Audio Playback / Your thoughts about the Sound Quality / HDCD on/off changes the sound on z0.9-6-1?

With z0.9-6-1 I notice a difference in sound when HDCD is activated vs when it is not. Iīm talking about music that was not originally HDCD, about music recorded with HDCD I donīt know yet. When HDCD is activated I find a bigger soundstage and the bass is deeper and tighter. I know we talked about it sometime before but now it seems to me quite evident. Is it possible that the sound of the no HDCD records could be affected just because the HDCD is on?
Peter, the volume with unattended works fine now, although Alt + D occasionally fails.
Still some tics in between tracks
Btw, I confirm the excellence of bolearyīs settings
