No problem at all. Such esoteric issues as the present one should be
less important than making the Touch work at all (which again

As I understand a TDR will get you a measurement of how clean the

cleaner edges (and therefore makes it more likely that the DAC

The Naim DAC has been mentioned on these forums before. It has a very
nice buffer-based design.
Can I just ask what your aims are in replacing the
cliveb: its primarily the house sound. Secondary is the possibility of
(official) upgrades.
My amps are Naim, so the balanced output option is not applicable in
the first place. I did try it in another setup, where it didn't work
particularily well for some reason.

The best way to check out the S/PDIF performance from a reflection
standpoint is to use a TDR. I don't have one setup right now, but I
should have one setup this summer sometime.

Yes + less electrical noise = easier for DAC handle accurately.
Apparently the eye pattern (what s/pdif looks like on an
oscilloscope) is very good indeed.

Thanks for all answers so far. Please keep them coming as things pop up
from the dungeons of your memories :) I was thinking that perhaps a
thread with hard Touch-facts (in this specific context) could be made
sticky for a while. This question does indeed seem to come up
regularly.

As far as digital output of Touch vs. Transporter goes, the only
somewhat credible statement I have been able to find is this by Sean:
I haven't been in the loop on this for a long time, but I have high
confidence that it was done well. The electrical part of it is
basically the same as

Thanks Phil. I was asking about RCA/BNC since apparently when ordering
from BJC, one can specify any combination of termination without extra
cost. So I thought that when given a choice between multiple products
at the same price - one might as well choose the best :S

If the Touch was not a lot better, I'd be gobsmacked.
Even the digital outs? Sean made some serious claims about the SB2
digital out quality (jitter and all that).
