Are Burmester Amps a good match with Aesthetix Pre

911 mk3 has very unussual electrical characteristics - very high gain (34db) and extremely low input impedance (2k balanced) - so if the 956 is similar in that regard, then it will not be optimal. A friend of mine was loosing tubes in his vtl all tube pre with 911 - the load was probably too severe.

I tried using a Conrad Johnson ET5 preamp with a 911mk3 and did not like the combo. The ET5 was heavenly with everything else but not the best match with my 911.

I have a match made in heaven with my 911 m3 and Concert Fidelity pre. Outstanding!
