mono block or bi-amps which would you pick?

Yes, zipost, let us know how you fared.

Mono blocks...
Do you hear an echo?

Zipost, I would PM Ralph Karsten (atmasphere). He builds, in my opinion, one of the finest tube amps and preamps available. He regularly contributes to Agon forums and is a source of unbiased opinion.
I trust his opinions implicitly.

Great move, zipost, let us know how it turns out.

Now that kantx resurrected this post.

I wonder how Zipost fared?

I, too, had a bad time with Sound by Singer. It wasn't the money, but the attitude. I can't believe they are still in business.
In any case, I hope to hear you review.
