I’ve been trying one out for the last 6 weeks fed from a Nagra dac into 009s. I’m coming from a 007tll kimik but also borrowed a t8000 for comparative purposes.
The new Stax unit sounds very similar to the old one, but a little more refined - lots of detail, rather bright, bass slightly improved. Not for me.
The Trilogy has a lot more body and substance with greater harmonic structure. Bass notes much improved over the Stax. High frequencies slightly rolled off but the detail is still there only less pronounced. This was designed with the 009s in mind which can sound a bit sharp up top.
I’m no electronics bod and have no idea if the circuitry is new, old or whatever but experience has taught me that advances don’t necessarily translate into sonic improvements. To me this amp is very musical and makes for long term easy listening which is what I’m after.
If I were living in the States I’d have the BHSE but over here in the UK living within 10 miles of the factory should something go tits up I’m more than happy. I don’t want to be shipping hardware across the pond or Iceland!
3 year warranty. Has to be used with remote as no buttons to press.
