Anthony, what's the rest of yr system?
Dohmann Helix
Terminator
Schroder CB
...?
Well, it's mostly a diy system, quite similar in constitution to that of
@kodomo with a lot of channels, mostly round, straight tractrix horn, and very big and very black. I've integrated six channel SET amps into each horn stack such that it is an active system with one amp per channel. It is not yet finished, but the end is in sight. Currently I am listening in mono and it smashes my previous pair of stereo box speakers so handily that I've packed them up and moved them on.
I have a couple of decent SS phonostages that I've built, one RC passive, another LR passive, but am currently underway with an all-out LCR passive build based on E810f and D3a tubes and all the foo components inside, iron from David Slagle and Black-Art Audio. I have high hopes for that when it is done.
Preamplification at this stage is various SS but I am also gathering parts to build some DHT pre's. These will be simple one stage amps aiming for optimal gain, low distortion and perhaps a little of that DHT extra that those old tubes can provide. The speakers sound fantastic with SS preamplification, so I am not entirely sure that the DHT pre's will be what is required, but I think they are worth a shot.
Digital source is Phasure NOS1a G3 r2r dac. I love it, couldn't find anything better when I tried.
Analogue sources are a Sansui TU-X1 tuner, which I rate as the single most beautiful piece of audio equipment I've ever seen, and the upcoming Helix 2 with Schroder CB and T3Pro. MC Anna as primary cartridge, although I will have to find a second if running two arms.
