what is the weakest link in my audio chain

Thanks for the valuable advice. looked like the next upgrade that can gives noticeable sonic improvement with minimal investment would be to use better speaker wires.

FWIW: 10 AWG is more than thick enough already. I doubt you can eek much more out of speaker cables unless you can shorten them. Room Acoustic treatment would be much more productive.

If yoy're happy with the sound then your Bryston amp has to be warm sounding since Paradigm Studio v2 has bright unforgiving tweeter (Vifa). One of the better bargains in speaker cables DH Labs Q10 is slightly on the bright side (silver plated in teflon) - you need to try.

Studio 40v2 is a good speaker but its amplified version is a great one. The difference is lack of speaker cable and good amplifier matching.

Yeah, try swaping out that HD power cord you're using for speaker wires with one run of adequate length 11 conductor sprinkler wire, or two lengths per side of 7 conductor, and see what you think! Then YOU'LL know. Good luck

This is a popular misconception, IMHO. I have the same setup as Benqsun, except I have 60's for the fronts instead of the 40's. I've owned mine for 5-6 years and brightness has never been an issue for me.

V1 tweeters were horrible and V2 are a little better but still on the bright side - I know I have 60s v2 and recently got rid of original $25 Vifa tweeters. You might find reviews describing Paradigm v2 as neutral or crisp but you won't find single one calling them "warm sounding".

If brightness is not an issue for you - great.

This is from "Audio Ideas Guide" review of Studio 40 v2 (link in Audiogon reviews):

"The Paradigm has a slightly more forward quality, but is otherwise a very neutral reproducer. That extra on-axis energy between 5 and 7 kHz can be heard, and if it were tamed by about 2 dB, the Studio/40 would be, in my opinion, a virtually perfect dynamic loudspeaker."
