Default best PC based audio analyser

Hi all

I'm looking to get a really good and accurate PC based audio test set. I've looked at RMAA (Rightmark) and truRTA. Is there anything else I should look at? I'd like to be able to measure RIAA, amplifier power and distortion etc accurately. I am on a limited budget maybe a $300 or so.

I have an outboard Lexicon soundcard which is 24bit/192 compatible. Would I also need to build a 20dB or 60dB ULN preamp for RIAA testing and noise testing?

Sorry for the questions but thank you for your time

regards

Rob

Not sure if they have what you're looking for, but someone else I'm aware of is Liberty Instruments.

Thumbs up s/w for analysis

These posts are helpful! I have been searching and searching for an accurate relationship between h/w and s/w, but you guys have been a big help. This Liberty and Lexicon, although I will need to look closer, seem as though they are products that may possibly be what I am looking for. I am attempting to view several sigs, i.e. two preamp outs, two digital out, two mic's, maybe more. I have been sort of at a standstill; either the s/w functionality is questionable, or the hardware quality or functionality is questionable... I'm sure you all understand where my conflicts are with this topic.
I considered m-audio, albeit for a very short time!
Measurement Computing, I did really consider this daq, but not so sure if it is designed specifically enough for pulling in audio sigs, plus their cards may be overkill as far as what I need, i.e. paying for too much horsepower in a card!
This Lexicon interface! - those of you that have mentioned this product...is this Lexicon a possible candidate for analyzing audio sig from various sources?
Thanks
