I use the TAD-150 pre and TAD-60 power amp. I just rolled in some Tung Sol reissue Tubes in the power amp. Made the music sound more lush and open. Plenty of solid bass... I am not sure what Bizzy-Bee is selling the TAD-60 at but, I bought for $900. I had a DNA-1 and the TAD-60 with 60 watts per side put the DNA-1 to shame...
