"The last bit I really noticed is that when passing the pure digital source through a tube line amp, (didn't have the luxury to try a stand-alone tube D/A where I did this) it predictably smoothed things a bit more, and made the Red-Book CD at least listenable. The up-sampled 24/96 via tape sounded absolutely glorious through tubes on playback."

Which from my (admitted) laymens knowledge means, you prefer the sound of higher harmonic distortion.


Specifically, even order harmonics. Only tube amps have this. Not a 100% sure, so don't take this as a fact.


Depends on the kind of tube amp. Single ended amps have primarily 2nd order, with all orders present. Push-pull amps have all even-order harmonics very nearly cancelled, it's almost all odd-order distortions.
LP's have very strong assymetric (i.e. even order and odd order both) nonlinearities.

Most studios know that recording at > 44.1 kHz is pretty useless, unless it is a recording for DVD-A or SACD purposes. All studios I know record simply at 44.1 kHz / 24 bit. There are no artists that I know of that record at 192 kHz to give the end user a fuzzy feeling

OK so with my home recording gear limitations I basically have two options:
44.1/16 bit or 48/24 bit
Which would you opt for and why?

If it is going straight to CD as-is then 44.1/16. If you plan to do any kind of manipulation first then 48/24.

Edit: fixed quites.

The video world works at 48kHz.

If you were just planning on dealing with CDDA, it would be better to work at 44.1/24 than 48/24 (EDIT: if given the option), no?

Linn Records offer 24bit 96Khz recordings

A lot of concerts on DVD have a 24bit 48 or 96 khz LPCM stereo audio track.

Is this just marketing or maybe when you need to do some post manipulation or processing it degrades the sound less at higher bit rates prior to downsampling.

I have done some AB comparisions with 24/96 vs 16/44.1 and the difference are subtle on certain music and not noticable at all on other music.

Was this AB testing or ABX testing? ABX testing eliminates the placebo effect. AB testing doesn't.

This was ABX, with 2 people accessing the differences and a 3rd changing source. 

Was using a wonderfull recording on David Gilmore Live DVD which has a 24/96 LPCM stereo of the concert. Ripped from the DVD and converted to 16/44.1 using Cakewalk and left as 24/96. It's one of the best recordings i have ever heard, highly recomended. Started me off in the interest of looking for LPCM music off DVD's.

Fair enough. I guess that the point of my post was to remind you to state clearly when ABX testing has been carried out in preference to AB testing. This forum can be a foreboding place to a newcomer so I thought I'd nudge you politely before any less forgiving members 'stuck the boot in', so to speak. We like to deal in certifiable facts. 

Cheers, Slipstreem.

You also need to provide numerical results to show that it is statistically significant.

Also, were the sources level-matched within 0.1 dB? And properly time-aligned?
