Pretty easy listening system using mostly valve equipment most of it DIY.
The Tannoy dual concentric drivers and there crossovers allow a broad range of sources to sound pleasing to the ear. They have a slightly old fashioned sound which you typically hear with a large bass driver. As they say about Tannoy DC's "Once heard hard to forget"
I listen to vinyl these days and the Nottingham Analog Dais TT blends perfectly with this system - It has a slightly warm tone, typically use a Denon 103D & Decca Blue cartridge. The Decca loves old school rock & grungy blues. The Denon loves classical and Jazz.
I've finished fiddling with this system, one day I'll get around to mounting the pre-amp in a suitable box and make the amps look slightly less frankenstein.
More than happy to sit back and listen to music these days.
If I had one suggestion
Enjoy what you have and stop lusting over equipment which in most cases is stupidly unattainable & ultimately fails to satisfy
Nice DIY work. I've become a real fan of DIY over the past few years and have built a number of speakers, amps, and preamps. I've also been interested in the DDDAC. What do you think of it? How many DAC boards did you use in parallel? Are you using a transformer output, and if so which one?
