Granite Audio Integrated 800 amp opinions

My system is as follows:
Tannoy 12 " reds 15 ohms...93db
I generally listen to Jazz and Classical
I just purchased this Granite # 800 single ended amplifier. It has 8 watts...300b tubes.
Is anyone familiar with this Amp?...opinions please.
No .
But I do have his 657 CDP . It has performed flawlessly for over 2 years ! Made the old fasioned hand in the U.S.
A great product from a great company .
I am sure that you will be pleased .

Would like to hear back from you about its performance .
Maybe a review .

Good luck .
