New to your forum, and relativly to the deCapo's.
I started out using the Musical Fidelity X150 and finally tired of the brightness this amp produces. Oddly enough, with another amp I probably would have ended up with other speakers, but the deCapo's sounded the best with this amp.
Have recently moved to the Arcam Diva A90, and it does truely have the British sound I have always known; as opposed to the MF and Naim.
The MF tube buffer is a wonderful product to use with CD's and a tuner; it doesn't smooth out the sound as much as a tube amp, but certainly leans in that direction. A definite option for SS users.
