Hello. Your post says a "good" preamp, which opens the door to many such units. I can personally recommend the Muse Model 3 Signature, a SS unit, which offers a clear, smooth, dynamic sound, excellent bass, and an HT pass through. This unit also mates well with the highly regarded Muse cd/dvd units, like the 9 Signature or Model 10.
You said a tube pre might go better with your Herons. BAT and Sonic Frontiers both offer high quality tube preamps with HT pass through, as do several other mfgs. A lot of people also like the Supratek you mentioned. I am sure you will get other recommedations as well. PS> if you are interested in the Muse units, e-mail me. Good luck-Tim
