It will not only sound better, but also be a lot more convenient.
1. Sony STR da5700ES Pre / Amp only as before...
2. Sony Pre into Bel Canto AMP (Theater Bypass)...
3. Bel Canto Pre / Amp on it;s own.
Not knowing anything different...1 was very enjoyable.
2 improved the top and mids....much cleaner / clearer, better soundstage, depth, lower mids into bass more "fuzzy / whooly" by comparison to 1.
3 initially sounded very bright on top....fatiguing...almost unlistenable on some tracks.
Left Bel Canto on with CD repeat for 100+ hours...
3 now is far better up and down the frequency range including the bass with bass cabinets set at "0". Rocket 33 speaker cables gave a nice boost to mids and tampered down the top just enough.
