I have an Ayre K1xe (used with a v1xe, and a c5xd into Vandersteen 5A's. The air is one great preamp. If you need more bloom place it on Ultam slab which will change the perspective a bit (put the instrument back a few rows in the orchestra, but still retain its extremely musical excellence. I suppose you can use Purist cables etc. to play with the balance as well, but the preamp as well as all their gear is a cut above.
