I used to own an all Spectral/MIT system driving speakers very similar to JM Labs Utopias. This system was extremely fast. The MIT cables actually opened the sound up tremendously,i.e., they did ib no way slow things down. The one complaint I had for this set-up was that it could have been a touch warmer. But, hey, this is THE big trade-off still out there, speed vs. musicality. The choice is up to you.
I have since been forced (economically) to downsize my system. I currently use a tube hybrid AVA Transcendence 7 preamp. This unit is in now way "slow". It is extremely fast (not as fast as the Spectral DMC-20 pre) with very good dynamics and bass control, all qualities I like in a system. Tubes do not have to be slow. Just do your research on this subject.
Hope this helps.
