feature set looks great, until I got to this
Rated output: 20W + 20W (6Ω), 18W + 18W (8Ω), 14W + 14W (4Ω)
That demands very efficient speakers, which I am in favor of, but by experience/instinct I like having 30/35 wpc minimum.
Highly efficient speakers, often horns, need/have large efficient woofers to keep up with the horns, so large enclosures, exactly what I have used with 4 different tube amps over the years, 30/35/35/45 wpc.
so limited to rooms that can handle large speakers properly away from walls/corners. Now, trying to fill that space with 18 wpc at 8 ohms?
wpc usually increases i.e. 20 wpc 8 ohm/40 wpc 4 ohm, this design is only 14 wpc 4 ohm.
option: efficient smaller mains, and a pair of self powered subs, directional adjacent to mains for stereo bass.
I would want 2 phono inputs, both MM, let MC be boosted via SUT or separate MC Phono. Keep phono more versatile.
