It´s really interesting how the sound changes as you get up or down the volume. I haven´t associated it to the SFS size however, but probably boleary is right. Hey, you´re really an expert in SFS and volume control and not only driving blue cars!.

By the way, take a look at the car, ok it´s 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!

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. I´m 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 boleary´s settings, which for me and so far are the best settings I´ve 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 that´s 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 I´ve 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 that´s natural, well delineated with great soundstage and not at all aggressive.

All in all a great way to rolling tubes without tubes.

Could this be the best device around to do the job?: http://www.10audio.com/prism_orpheus.htm

Hi Bert,

RCA output: 1.5V RMS (-3dbFS relative to normal Full Scale)

XLR output: 2.7V RMS (+3dbFS relative to normal Full Scale)

I sent you the manual via mail to the contact you have in your web site.

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 don´t have a big Lp collection, maybe around 500 that are worthwhile, some of them also in cd. That means that I don´t want to invest a big amount in hardware or software, what I´m 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, it´s very cheap and even sell a TT, I don´t know about the quality, however:

Once I have the TT how can I do it?, I mean digitizing vinyl

Thanks, Juan

Ok, maybe there´s a good idea around on how to do it with the best possible quality.

Juan

Could anyone recommend a TT with USB for transferring my LP collection to the computer?.
I sold my TT some time ago and now I´d like to transfer the LPs to the computer. Any recommendation about the TT that could do it directly to the hard drives (WAV files)?.

Here you can read a review where TNT Stoneblocks are tested against Polychrystal and others:

Just in case some of you don´t know other points of view, mostly about different materials and even no boxes at all, here they go:

Talking about lacquer we all know that the good concert pianos are finished with many lacquer layers. My speakers also follow this path and they have several lacquer layers applied.
 

Reading the previous TNT reviews I´ve found this interesting article, "Wood is good":

Hi Peter, have a nice weekend, this is the first attempt to find out about what you´re talking about:

If it´s not what you are talking about it´s very interesting to read anyway.

When the music reproduced is HDCD there´s a volume change in playback, so that's easy to detect, also if it is HDCD the logo appears while charging it.

I had the feeling that the soundstage was bigger with different discs that were not HDCD. I don´t know, maybe it was a false impression, I'll look more closely

I'm not sure anyone wants me company to play the same song ten times (or more). This hobby is for loners

Well, once in a while...maybe

With z0.9-6-1 I notice a difference in sound when HDCD is activated vs when it is not. I´m talking about music that was not originally HDCD, about music recorded with HDCD I don´t 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 boleary´s settings

Too much pressure Flecko, as I said she´s shy
