Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Srajan once told me he was very fond of the Allnic cables. Seems like a company with a good product line up. 

@yorkshireman As you'll no doubt see, prices can be all over the place for various SET designs. Charles rightly points out that the circuits are simple, so if you can, look for "under the hood" pictures that show you parts and power supply quality of the build.  If you're not confident evaluating, then post links here and I'm sure many will opine.

If you can at all swing it, I would recommend mono-blocks (or a single chassis dual-mono design).  I built my own amplifiers (from pre-made Nelson Pass boards), and the change in sound quality when going from a standard stereo build to a mono-block design with independent power supplies was quite substantial.  There is good reason why all cost-no-object designs have independent power supplies, as the two channels create distortion when they are simultaneously pulling on the same transformer.

I know the more expensive Allnic separates use point to point wiring but the integrated amps use a PCB.

There's an image of the inside of a T2000.

KS Park told me that the T1500 also uses a PCB, so probably very similar.

I've been using an Allnic T2000 which uses 4x KT120 tubes at 50-100W (Pentode/Triode) which was OK but I think was maybe too powerful and has maybe been damping things a little.

I've been trying (just as an experiment) my old SS Olive Naim Nait 2 20w which doesn't actually do a bad job.

I know purity of signal path is very important with tube amps.

I suspect that the internal environment of the T1500 is less crowed with fewer parts as SET is simpler. Higher power push pull amplifier will have a higher parts count.

@yorkshireman You are welcome. If you are still considering options...please know that I’m not trying to dissuade you from the Allnic T1500...here are a couple of avenues that may be worth exploring.

Audion Audio’s (UK; with France based office) Silver Night integrated line. Their entry level utilizes a PCB, but are point to point hardwired above that level. Known for their 300B version. Used upper levels units may be within your budget.

If you want to specify the build and parts, then look into Ken Uesugi of Sound Gate / Otomon Laboratory (Japan). Vintage chassis / looks, if that’s okay with you. He sometimes lists on Audiogon. He should be able to deliver within your budget.

And a +1 to @cal3713 ’s post.
