Well there are numerous unhappy owners including myself but in the end I knew of others prior to my purchase but thought they were over exaggerating but found out first hand they weren't.
I purchased a brand new pair of JL3 Sig. MK2 mono's.
Prior to placing my order a date for delivery was promised and confirmed, even though the time frame seemed long I went along with it. I then had to pay 100% prior to the actual order being moved ahead and active.
Well long story short the time frame came and went and took months longer.
Upon opening them up found scratches and other issues, wasn't very happy seeing that.
Had issues biasing one amp, would not hold a bias. One amp almost blew up and thought it had taken along my MBL 101E speakers.
I know everyone else in the home came running wondering what happened.
It was a complete nitemare dealing with the owner, took a year of the amps going back and forth for one reason or another and in the end were left there and then put up for sale and lost money but got rid of a major headache.
Sound was pretty nice but I would not say Smokes most other tube amps as you mentioned in your posting.
The matter fact VAC smokes them, I currently have a pair of the VAC 450 Statement mono blocks and the sonics produced are in a whole different world, never mind fit and finish and reliability.
I'm very happy indeed and has finally gotten me of the merry-go-round.
I would never recommend this product to anyone, I am privy of many stories but if you want that info. best to PM.
