Legacy Audio Powerbloc 5

@kraftwerkturbo-tt225 both posts have links to specs. 

Yes, I saw the basic specs, thank you. 

So on paper seem to be a decent amp. 

But very obscure given the little info that is out there. No test, no review. No for sale listings. Can always call it 'rare, hard to find' when reselling it if it is junk and/or sounds horrible. 

And REVIEW or TEST available? 

Debating if I should fetch one for $500 from local store. Vs for example an Adcom GFA-555 I could fetch for $250.
