Hi Presto> when using foobar, I prefer to do no upsampling *IF* I am doing convolution or PC crossover plugins. If not doing convolution, then using the PC for crossover functions is fine - quite good sounding actually.
~ Due to over high demands on the processor, causing pops etc?> If doing convolution, I prefer to use outboard passive crossovers (or at least an outboard digitial active crossover). It seems that once you start doing more and more *different* digital processes (aka plugins) it seems the "effect" of doing all this processing seems to be cumulative.
Another approach is room correction with a Behringer DEQ2496 street price $300??

which would free up resources for other things> Upsampling seems to have a high "penalty to performance" ratio at the best of times, where convolution offers far greater benefits and a surprisingly low penalty.
Is the penalty ~ pops etc?

I own a Behringer DEQ2496. Performance in the digital domain is excellent when going from transport to DEQ2496 to external DAC. The DAC in the DEQ is not bad, but not outstanding either.
The DEQ only performs room correction so far as it changes the amplitude of the signal; it does nothing with time and phase as DRC does. The DEQ is very good at reducing room nodes caused by standing waves and can therefor offer good improvements in the bass. It has many flexible EQ stages, including an excellent parametric EQ, but that is as far as it goes.
Thanks for the veery informative postsPardon my ignorance, but is DRC ~ a plug in?
No,DRC is an acronym for digital room correction. There is also an open source software package called DRC that is used to create the listening room compensation correction filters that can be used by other programs to modify digital music on the fly so that it is correct for your room. You can check out the link below; just prepare to spend a week or two if you really want to learn more about it. You can also check out the wiki at http://www.duffroomcorrection.com/wiki/Main_Page
