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.

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.
