I need a quiet tube amp

Tom: What's your price range? I have had two different ASL integrateds: An MG si15 and a FOX Ki22, neither of which would be a good match for your Proacs. However, they make some other very powerful amps, but the 200 watt hurricanes are about $5k!

You simply don't have enough headroom with a 300b amp (about 8 watts). With your speakers, I would want something like a VTL ST-150 or a pair of Rogue 120 Magnum monos. That's a lot of juice, and I'm willing to bet you a burrito that your Proacs will let you hear things that you never thought possible!

Tomyran, I don't have issue with Sun Audio SV2A3 in my setup ( I borrowed this amp from a friend of my ) Definitely no buzz or any noise. with my Citation I preamp.
I'm using it with Jensen coaxial speakers and they sounded fine except for the bass. I prefer deeper and larger volume of bass from that 2A3.

Tomryan,

I do not know how a 300B amp compares to my Audio Note Soro SET amp that has 6L6 output tubes but my amp is only rated at 18 watts and easily drives my Trente speakers that are rated at 88db - to about all they can handle too. Watts ain't always watts as the Soro sounds like it has about 80 of them instead of 18.

I strongly urge you to look into one as I got mine for only $1300.00 and it has a terrific phono section as well.

just my 2 cents...

My Klipschorns are efficient and will present the noise of components ahead in the chain. Today, I am running two older units: Conrad Johnson MV75A1 tube amplifier and a Marantz 7T solid state preamp. There is some low level residual noise in the MV75A1 when played without the preamp being powered. When the 7T is powered, there is slightly more noise ... mostly hiss. To hear the residual noise, one must be within 2 feet of the mid/tweeters. Beyond 2 feet, the noise is not audible even beween tracks with the volume at near pain levels.

Crazy4blues - You owe me a burrito! The first two years of owning the 2.5s I had a Mesa Baron 150wt tube amp and have also used a 150wt SS and 25wt various tube and SS amps. The ProAcs sound best with the Air Tight ATM300 but, again, they are a very easy load, I listen in the relative nearfield, and my room is small. I know exactly what you mean, though, as I've gotten subtantially better bass from them and that's why about two years ago I bought a REL subwoofer. Tube and especially SETs sound far more powerful than the simple wattage rating. The SS Muse mono 150s never did sound powerful since the music just got louder, it didn't get more, um, "musical", if you know what I mean. I think that's why we all have tube amps.

And I know what Phil means since I've also owned 572 SETs which put out 15-20 wts and they drive the ProAcs wonderfully with deep and well defined bass. They actually did more realistic bass than the Mesa which simply pounded the bass region harder and louded.

I use a Placette remote volume control instead of pre-amp as I've also tried a bunch of those and even owned an $8,500.00 tube job. Nothing sounds more direct and transparent than what's being used now. (Hey, where's that guy who used to tell us we have to spend $15,000.00 to get a proper pre-amp?) A pre-amp will add another gain stage which may likely make any noise louder, if it doesn't add it's own.

I'd like to spend about $2,000.00 for a used tube amp and have been checking out various ALSs and ANs but, unfortunately, looks now matter to me so it's taking more time than it should. I'm havin' fun, though!
