Pass labs X600


Hello

I would like to know, what amp from another manufacturer is comparable to the Quality and potencial of the Pass X600 regardles of price. What amp can be consider to be as good as the X600. I'm in the market for a pair of monoblocks, but seems that I won't be able to find any X600 any time soon, so I need another options? Also what make Pass labs X600 so heavy? is it worth the weight?Any help will be apreciated before I make a decision.

I know a guy who did just that. I bought his X600 and later sold it for an Acoustics Reality eAR, only to be sold for H2O monos, my present amps. Each change worked wonders.
Yes, I would check into Henry Ho's H20 monos also.
I have heard some great reports about them!
