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

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.

@david_ten - Thanks David.

@yorkshireman  Do you have any updates?

Came across a strong recommendation and stellar pairing synergy for the Bakoon AMP-13- and HiFiMan's flagship Susvara planar magnetic headphone. I own a previous flagship, the HE1000. Mentioning this because it gives me insight into the Bakoon - Nenuphar synergy.

FYI, both the 13R and Susvara retail for around USD 6K, each.
