Vincent SP-331 Amp Review

I have previously only used Receivers with this being my first separate component. At this point Im venturing into separates one step at a time. Im using the Vincent Amp to power my front stereo channels of my B&K AVR-307 Receiver. With that said, after listening to the amp at my dealer with similar speakers to mine, I decided to take the unit home. After first listening at home to the same CD I played at dealer. I was wasnt to impressed at first. Then about, 2.5 hours later everything came together. Stereo imaging opened up, the sound stage was full bodied with detailed instrumentation. I can honestly say after listening to several of my CDs which Im familiar with, on some of the discs I have heard details I have yet to hear before. Maybe a guitar and keyboard in the background. Im enjoying this Amp and it seems to sound even better as it warms up, say after you go through 2 CDs. Currently just upgraded to Kimber Hero interconnects amp to receiver. Next step will be an upgrade to the AC power cord. These small things are for peace of mind, rather they increase performance can be questionable.

One of the true bargains in Audio

I have owned a healthy number of power amplifiers, buying each one, using it for a year or so, and then re-selling it -- all in the search for an amplifier that manages to provide both tight, well-defined bass and also clear, articulate treble that does not cause violins and flutes to shriek in the higher registers. Oh, and that I can also lift and move without a wheel barrow or hiring a weight lifter. In that search, I have owned amps from Conrad-Johnson, Audio Research, NAD, Nelson Pass First Watt, VTL, Exposure and Musical Fidelity, among others. And the first power amplifier I have ever heard that manages to completely meet my criteria is the Vincent SP-331, which cost roughly 1/3 what a couple of those other amps cost. Its hybrid design -- using tubes in the input stage and solid-state output -- provides articulate bass, smooth highs, a detailed midrange, and very respectable stereo imaging -- although not on a par with VTL or Audio Research. The simple fact is that you will not find a better amp at anywhere near this price -- and you can pay a lot more and get less. The amp does have its foibles, which is why I have given it only four stars. It takes a good forty to fifty hours of playing time to break in. The binding posts on the back for the speaker cables are not true WBT -- they can take banana plugs, but only by placing the plugs in the large post holes intended for bare speaker wire and tightening the lugs. You cannot plug the bananas into the back of the terminals. The tubes are not user replaceable, so while they have a very long projected life of roughly 15000 hours, at the end of that life or sooner if you get a bad tube, which can happen, you are going to have to hope you can find someone to service them. Vincent also does not include any warranty information or a warranty registration card or online registration services with the amp -- although Audio Advisors -- who I trust -- tell me that the amp has a two year warranty and service can be arranged through them at Vincents service facility in Grand Rapids, MI. The fact is, though, that Vincent, which is rumored to be owned by Thorens, should know better -- they are required by federal law to include warranty information with the product or advise where it can be found online -- and they dont. All in all, a remarkable product at a very reasonable price. Do yourself a favor -- if you have less than $5000 to spend on a power amp, dont bother to spend more than the price of the SP-331 -- get the Vincent and spring for better loudspeakers, instead.

This Vincent has Vincent C. impressed with the music.

This Vincent Audio SP-331 has me in awe with all you get for so little. My Magnepan MMG loudspeakers which are a none friendly 4 Ohm load is driven effortlessly, and sound is amazing for the price. Midrange the most important is very right, with no harshness. Actually Midrange on up the SP-331 is so smooth without sounding slow and veiled. Bass is taught and timbre accurate. Stereo sound field or soundstage is tops in depth and width, with a layering of the Orchestra that is well close to true 3d. This Amplifier makes other amplifiers in its range almost illogical to choose. Though many may have the Vincents power supply which is huge to begin with already 80k capacitance and a huge 1kva plus Toroidal Power Transformer and 12 Toshiba output devices per channel, the other amplifiers dont have the Russian 6n16x2 in the pre-driver stage. I think that is a big plus to give the amplifier the character I really love. Build is very good too, and with only the spaced too close RCA Phono connections to carp about, that is high praise indeed. Everything else is so musically right. Should be on any music lovers shortlist of amplifiers to audition at this magic value level. Hint, I have had NAD and Rotel at this level, and the Vincent is vastly superior. At least to my ears. Give the Vincent Audio SP-331 a listen.
