If you are in to DIY, try Dact CT101 (or 2 for balanced output). Aleph is a littte "shy" in the lower octaves and the Dact have a little more punch, in any other freq. is Dact pretty neutral. Have a pal with Martin Logans, Aleph 5 and Dact (NLE in scandianavia). A match in heaven.
Matching preamp for Pass Labs Aleph 5
Looking to match a preamp with the Pass Labs Aleph 5 (60W). My CD is a Naim CD5,cables are Cardas,and speakers are Audio Physic TempoIIs(a little bass shy and bright). Something active or tubed with warmth and detail. Tried a Pass Aleph L passive but flat in the lows among other things. A tube preamp must have higher output impedance since the Aleph 5's input impedance is very low (14 Ohms). Thanks
