Usher R1.5 should I buy?


Hello all, I thought this is one forum where I should ask and take the approval of all the experienced souls here before I pull the trigger today or next week satday. The Question is should I buy the Usher R1.5 , is it as good as the press says or the reviews here or around the web suggests.As for speakers I have a Mission MX5 for now with Denon PMA1500AE /DCD1500AE/TU1500AE as amp CD and tuner with Chord cables. This is the cheapest power amp I can afford at the moment , that too class A till some watts. If anyone has any encounter with this amp please advise me. I listen to only RocknRoll and very little Jazz ( read Norah Jones , Diana Krall) buy it's always Queen and Ledzep , Floyd GnR, CCR,GFR,Lamb of God Korn , Blue Man Group, etc etc. I'm a SACD enthusiast,s o no vinyl in the mix. Love warm rich lush and not forward sounding gear. Please advise if the Usher is good enough as a power amp.

Usher R1.5 and R2.5 were almost direct copies of the Threshold Stasis  S200 and S300. I showed Nelson Pass the circuits of the Ushers, and the only difference was they had one extra gain stage transistor in them, which Nelson replied was what he would have done if he did a re-design of them.
So your in good company as I owned an S300 mkII and it was a very nice smooth amp with plenty of grunt.
