My Burmester 911mk3 mono amps have not arrived yet, probably another month. I've been using my Dartzeel NHB-108 mostly and have given a fair amount of time to a CJ Pr. 350. I am absolutely convinced my Dart amp is probably the finest amp I've ever heard. I sit in amazement every night at how much enjoyment the Dart 108 gives me. I've been using a Burmester 077 preamp, which I think is a fine preamp, but I will eventually be trying either a CJ GAT or hopefully/eventually a Dart NHB-18NS. I believe the Dart preamp might eventually win because I think it will match better (especially with the 50 Ohm zeel connector). I like the CJ Pr 350 but the Dart 108 is so refined, so natural and pinpoint specific, I love it. It works extremely well on my TAD CR-1's, much better than I thought possible. I was worried about matching the TADs and the Dartzeel 108, but the CR-1's do not seem like a tough speaker to drive, thankfully.
I was able to acquire a Conrad Johnson GAT preamp to mate with my Dartzeel 108. What a great combination. I absolutely love them together. I can imagine the Dartzeel preamp is superb but, I've always wanted the GAT. Everything sounds great through GAT/Dartzeel combo. Very natural, female voice especially sounds right to me.
RCA from GAT to Dart. I'm using Cardas Golden Ref. one meter IC's. I've used Transparent Super XLR's from my 077 with excellent results as well. My Dartzeel 108 is a fully up to date version A.
RCA is the way to go, specially with version A.
Can't you send it for an update to version B?
BTW, the dealers here keep sending different amps for me to test, but nothing beats the good ol' 108... I'm just done testing Audiopax's latest Maggiore 100 amps (100W single ended class A1 monoblocks), and while they were indeed wonderful, as soon as I put the 108 back, it was pretty clear the resolution was cranked up a notch! And these are US$ 60k/pair monoblocks... That's why I don't think these Burmesters you have coming will stand a chance
I believe the A version is the better sounding unit. The B version has an auto dc compensation feature that can be turned off for better sound and also has additional wire in the xlr circuit that can degrade the sound as well. This is why I picked the A version, plus Herve thinks it sounds better. I am curious how the 911 monos will stack up against the little 108.
