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!

As already mentioned, the Burmester amps are typically designed with balanced-only inputs, have unusually low input impedance, and run at very high gain. This makes them difficult or impossible to run properly with many tube preamps. I am making a device called the Flex-Connect that overcomes these obstacles and allows any tube preamp to run these excellent amplifiers properly. Please see my website for more information.

Burmester amps are glorious if matched with Burmester Preamplifiers, even if they are the cheapest/older ones.

I tried to match my 911MK3 with my faithful Mark Levinson 320S, not bad , but the Burmester preamp was the match made in heaven.
