Solid State Preamp to replace tube unit

@tomic601 -- I have bought from Brent Jesse when I was getting tubes for my new Reisong A10 (absolutely amazing little amp -- I saw a review by Steve Guttenberg and thought "What the hell".  It cost me a total of $345 and that included shipping!  Paid another $120 for upgraded tubes.  Awesome amp for my bedroom streaming system).  I looked at your pictures...beautiful.

@elliottbnewcombjr -- I agree with your comment!  I try to keep a back up set of tubes for all my amps and preamps -- the MC225 is the only one I haven't purchased them yet.  Your suggestion makes great sense...start using the new set and keep the originals as back ups/nostalgia.

@dogearedaudio -- I bet those monoblocks were sweet.  I've seen a couple for sale and they aren't cheap!  And the tubes aren't either!

@ Jimbones

My personal experience - I have owned and loved playing an Ayre K-5xeMP preamp for many years.  Eventually, I wanted to try a good tube preamp and bought a ARC Ref 6SE.  

A used Ayre K-5xeMP now costs 1/10th of the new ARC, but is surprisingly good for the money. It is different than the ARC, but it has the clarity, tone and voicing of a high-end preamp, but different sounding than the ARC (SS has a little faster attach and decay).

At this level, you may want to demo a few to see which provides the best sound (to your ears, that day) with YOUR other gear.  If I were buying a used SS pre, I would also look at Pass and Classe, yet knowing what I know, I expect that the Ayre outperforms, dollar-for-dollar. 

Have you tried Accuphase Pre in the use market? The sound of Accuphase is very seductive, part SS and part Tube. I think you can get a used pre around your budget. I don't have their pre but I have their amps. Both class A and AB are both espectacular when I compare them with my McIntosh MC611 and MC1502 tube. A lot of detail without being harsh or analytical. I heard their Pre are the same. 

@rubicon15 just bought some new Teslas. Lets see how they work out. In the past i used to buy from Andy at ATS and Brent Jessee. They are good but there is no guarantee you are getting new tubes and most are older used tubes. That may be why I get shortened life

@inagroove Would you still consider Classe? I heard they are out of business again. Also, I heard that the engineers that they had working just before they closed was to finish some work so I am suspicious that their efforts may not be their best.
