Has anyone heard the Usher Threshold R 1.5 amp?

Mboldda1 - what amp did you own previous and/or what other amps have graced your system in the past?

before the usher ihad the denon pma-2000ivr integrated used as a power amp with dodd audio entry level tube preamp.

I actualy own an R-1.5 and using the usher p-307 pre-amp with its own power supply.
The reviews ar bang on for this combo, they work in great symbiosis together,a good complement.
great dynamics with a unfatiguing sound, very tube like in its presentation.
The sound is detailed from top to bottom, its a very good combo for the price.
I reccomend an audition for anyone searching separates in the neighborhood of 5500$.
