Need some advice, Vincent Audio

These are the tubes I used in the SV-237:

Tung-Sol 12AX7A - long gray plates, halo getter, phono grade

Voskhod 6N1P 

That really smoothed out the sound and improved dynamics. 

I've always been curious about their amps. Good to hear these positive comments. They're often available used for reasonable prices.

I have the Vincent SV-500 coming up on 2 years now.

Really nice and smooth. I haven't tried any tube rolling but I also haven't felt a need to. Everything from Vinyl to Digital sounds great.

I am thinking about perhaps getting a amp and using it as a pre-amp but have also pondered about upgrading to the SV-237MK.

The new 737 looks like a beast for sure.

I feel like Vincent is one of the best value products out there.  I have owned more integrated amps than I should admit to (McIntosh MAC6700, Esoteric AI-10, BMC C1, Pathos ClassicOne MKIII, Teac AI-3000, Cambridge 840A, NuPrime IDA-16, etc.) ...and I keep coming back to Vincent (I have owned the SV-500, SV-236, SV-236MK, SV-237).  I have also owned/enjoyed the SA31, SP-331, and SP-10 separate amps.

The Vincent SV-236MK & SV-237 is the piece I have recommended to more than a dozen friends/enthusiasts and they've been equally as thrilled as I have been.  And the Vincent PHO-8 is, in my opinion, one of the best MM phono preamps you can buy for the money.

Anyway - in case it wasn't apparent, I'm a huge Vincent fan...I wouldn't hesitate on the SV-737!

I have owned SV-737 for 2 weeks now, driving Gershman Sonograms. Fantastic sound, huge stage and dynamics I never though were there. At this price point you'd have a hard time finding anything comparably sounding even on the used market.
