You know, I don't recall if I came across someone comparing the two chips at a granular level, I haven't read into it deeply, but most say the PCM63 is "better", but the PCM56 is not far behind, both well-regarded tonally from my reading. The PCM63 is a 20-bit chip compared to the PCM56 which is a 16-bit. BUT once you get down to bit 15, 16...and beyond, the DAC needs to be well-engineered otherwise noise will dominate at that bit depth, you won't hear the extra bits anyway! So I wouldn't think the difference is due to dynamic range. Another example - the PCM56 is generally more highly regarded than its 18-bit counterpart, the PCM61. Notable also - the PCM63 does have better distortion specs than the PCM56. If I get serious about messing around with PCM63, will look into the subjective differences further.

Another thing though - the PCM63 is becoming quite rare, especially the best binned "K" grade, even the "J" run almost $100 a piece, you need two, whereas the PCM56 is very available and cheap. Better for experimenting

Batteries my son. You have to use batteries. Theoretically with batteries and low noise Jfets, you could reach down to 24bits of dynamic range.

One of my projects before the year is done is to build an all in one headphone system that uses batteries and low noise jfets to achieve a true 24 bit system.

Is it stupid? Yes. Why am I doing it? Because I can.

Anyone have a use for these tubes?
NOS 6SG7GT/JAN-CNU National Union

I have 14 of them if someone can use them.
Never used in original boxes.

I personally don't have a use for them, but thank you for offering! Maybe someone else does, I'm actually trying to buy less tubes as I have no space for them lol. How did you end up with fourteen?!

Guy was selling them in sets of 6, I bought 2 sets and he threw in 2 extra.
I bought these by mistake last year ( I thought they were 6SJ7GT without my glasses on) and I have had them in the box since. Clearing out some clutter so offered them up to anyone interested.
I'll put them out on the classifieds....thanks

Awesome excuse! Hope you have no copyright as I am gonna start using that one

Gotcha, might try eBay sold as a lot, not really an audio tube so might have some trouble moving them on Head-Fi!

I thought it was a pair of General Electric 12AU7, turns out I bought a pair of NOS Western Electric 300B, where are my damn glasses!

(P.S. I wear glasses too, so I feel your pain).

$199.95 is awesome price for those!!!!!

If you have a 12 volt switch on your OTL...you could use these

I am told the Audial DAC will ship Wednesday, international express so should have it next week. DAC parts should be here too AND I will be on a week-long staycation. Should be a good week of DAC shenanigans! Very excited.

Yeah. I'm getting mad. Or jealous. Or something.

I hope you still haven't found your glasses when the credit card bill arrives.

LOL I think I'd go completely blind from that point forward.

Right in time to help me scratch the DAC upgrade itch...
Cannot wait to hear ALL about the S5, your DAC, and DAC shenanigans in general.
