Integrated amp for efficient speakers


I am looking for an Integrated amp in the $1000 range to push efficient speakers (8 ohm). Considering YBA, Cayin, Sim Audio, Rogue Tempest, etc... Cayin seems to garner good reviews and satisfaction but the downside is hard to bias. I don't like a cool thin sounding amp but like neutral to warm with no listener fatigue. Right now I have Tyler Acoustic System 2's but will be selling those and going with a floor standing monitor like Ty's D3's with a sub or a high efficient floor standing full range (8 ohm). I have gravitated toward tubes the last couple of years for obvious reasons but not ruling out solid state integrated amps.

I'm a dealer for Cayin. The 50T, 70T and 100T are very easy to bias. It is all done from the top of the chassis (no need to go into the circuit like the 88T). They do not sound cool and thin. They are also not overly rich. They are very musical with a high degree of transparency and resolution.
Which Cayin is the sweetest sounding? 50T, 60T, or 70T? I also see the 30 with the Busy Bee mods.
Samzx12,

I am using a Cayin TA 30 with my new speakers,
Cardersound Madison's with excellent results.
It is the Bizzy Bee modded version. I love it
because it sounds great, is dead quite, (96 db) and
it a tube rollers dream due to the super easy biasing.

The 50T is the warmest sounding. The 70T is a bit more open (more spacious stage), transparent and dynamic.
