Upsampling the way to go? ?

Some of these go back a ways: MBS Full Nelson, Millenium #1, Dodson DA-217 MK IID, 47 Labs, Audio Logic, Kora Hermes, and Audio Note and at least a couple of others. BTW, the Audio Note, the cheapest DAC 1.1, SOUNDED the best. I have the Audio Note 3.1 Signature. Jim.

Up and oversampling ala GamuT CD-1 Danish CD Player- better then twice DSD sample rate. $2950, see review in The Absolute Sound. I just got mine, and am loving it!!!!! Huge 3 D sound stage.

With respect that's nothing but a number. I believe the earliest bitstream DACS had a sampling rate of 11.2 Mhz, 10 years ago.

I've also heard it said that soundstage is simply a product of frequency response, re/up/over/whateversamplers thus simply alter the tonal balance to achieve a "better" (according to the tastes of the beholder) sound.

Anyone interested in reading a little more about the process of upsampling, oversampling, interpolation, dither, etc. and how it can benefit(or hurt) the musical signal may find this interesting from the Perpetual Technology folks(see link below--sorry if someone else already referred to this). I found the Level III explanation(see link at the bottom of that page) to be the most interesting and it doesn't take all that much time/effort to read. What I took away was that it seems like it is the companies that go to the trouble of creating proprietary interpolation algorithms to meaningfully increase word length(i.e. not simply just adding dither) in addition to the upsampling that are the ones that are really taking CDs to a higher level with this concept(obviously a lot of non-upsampling players sound fantastic too). In addition to the PT P1A, the Audio Aero Capitole(STARS system) and I assume the dCS Purcell do this to great effect--anyone know what Electrocompaniet does with the EMC1(24/192)? This makes sense to me, but it also again makes the important point that all upsamplers are not created equal--not by a longshot.

This has been interesting reading, but no one has answered the question if they have heard a ARC CD3 compared to one of the upsamplers. To me the truth is still in the listening, not the stats.
