Amp for Harbeth P3ESR and Cambridge Audio Azur 851N

What about adding Vincent SV-500? SV-237 is quite high price above $4.5k. Not prepare to spent that on this set up. Just not sure if SV-500 will help in my setup.

You might be thinking of the newest Vincent SV 237MK, however it retails for about $2,400 USD (are you in another country?), not $4.5K.  The unit I bought was a second hand Vincent SV 237 (no "MK"), the previous generation.  I paid $1250, or $250 more than the SV 500.

Stary i’d Give skip @ audiothesis a call, he’s in Arlington, tx., I’ve heard him demo many a harbeth on quite a few different amps including mastersound, which was great! he might have a nicely used demo..

@big_greg: I thought you are referring to SV-237MK. SV-237 is very hard to find in the resale market. I did a search online last night, i couldn't find any in US. But, anyway, thanks for your advice. It seems that SV-237 is a really good amplifier with great sound quality highly recommended by many. I have nit heard it myself. If the cost is around $1k, i think i will give it a shot. Thanks.
