hi would recommend a CAT pre or even a sonic frontier SFL2. try cables like XLO signatures. if u biwire, try using an xlo jumper and save a pair of speaker cables. these changes on my system made the highs wonderful and then listen to "house of the rising sun" from either the opus test cd 4.1 or Eric Bibb/Cyndee Peteres opus cd. current user of Teac tpt, Jadis DAC, SFL2 pre, Manley power and Sonus Faber Guaneri speakers.
