asrc not good; should use integer multiples. Maths difficult especially real time.
src has plenty of images compared to good programs such as Audition. Thus
intermod.

I'm planning to try Audition.
With Foobar 0.8.3 and SRC anyway, 24/96 sounds better to me than 24/88.2
Steve N.
I am not sure if it can be generalized, my preference (not with SRC SW but other upsamplers) was 24/88.2 over 24/94.
Based on my limited experience, I would say I prefer synchronous oversampling over asynchronous.
Also, this is very subjective, for example, an audiophile friend of mine and I converged over time to almost identical systems, we have the same speakers and amplification, but we disagree on digital source. He is in love with sound from his Esoteric player while I cannot stand it. Yet we both agree that his (our) system sounds the best with source being analog tape.
And if you look at previous thread on Lynx L22 sound card, after I set WaveLab with ASIO, I found digital out of PC/Lynx better than my optical transport in many aspects. It has some "analog" qualities. My present optical transport is nothing special of course, yet I found it vastly superior over SB3 at the time I was playing with it, while some consider SB3 sonic heaven.
So I will pursue further PC/Lynx as transport, by isolating sound card in same sort of a cage, will try to find a way to remove switching power supply from PC and replace it with something linear regulated, and will make my own break-out cables out of sound card.
The result will be different with each upsampler and on the computer even each player and plugin for ASIO and KS etc.. will have an effect. Each system is different with it's own set of weaknesses too.
There are no separate clock domains in software upsampling, are there? How can it be asynchronous? And with hardware upsamplers, at least the devices typically labeled as upsamplers in the audio world, unless there is some bypass mode they are always asynchronous since there are two clock domains which will never be exact integer multiples.
