Banana plugs arrive tomorrow, but I am out of the country for work until Thursday 🙁 So I will try to get some listening in as soon as possible.
I can give feedback from my audition though... I went to Sevenoaks in Guildford.
The Audiolab MDAC+MPWR combo was good. You could tell it was good quality, well built, nice display, decent remote control. Sound wise it was very clear, very open but far too bright for me. I think Audiolab + Kef is not a good combo. It exposed lots of detail in the music but it would give me ear ache after not very long.
The NAD 356BEE DAC was like being bludgeoned with a large mallet! If I was 20 years younger and had lots of house parties then I would have chosen the NAD. I always felt like I had to turn it down, but it still felt too loud! It is warm, bassy, muddy and loses lots of detail - but it does make your foot tap along to the music. Not for me though.
The NAD and Audiolab systems seemed to be two opposite ends of the extreme. The Leema on the other hand was much more balanced and natural, with lots of detail and just sounded very enjoyable.
