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.

My mail id is right there and I have the schematics as George mentioned. What pre are you using desalvo55? I'm using a Cary Audio SLP03 and the results are pretty darn good. I have got to know that the factory Bias of the R1.5 is 500mA. So keep that as a reference point. These amps are simply fantastic and can be easily repaired by anyone who is experienced enough. Usher is going through a restructuring hence the delay.
This amp is fabulous once mated to a proper Tube Pre Amplifier. Will uproot a $6000  McIntosh in Dynamics and Heft.
Thoughts on pairing this amp with a Modwright pre-amp ?  I'm thinking of going that route as i currently have a Modwright pre.
Just bought a pre owned R1.5 and listening to it for the first time.  My speakers are USHER 8571 II and thy were a bitch to drive. So far so much better with the new amp. I am using my old Rogue Audio Pharaoh as my pre at the moment but thinking of a tube pre...  any suggestions out there???
