I really have been under impressed after upgrading from the Meridian 861 V4 / 621 combo, to the V6 this past Spring. When I think about the $16K upgrade price tag, the nauseousness really sets in. Certainly at some you hit the point where the extra dollars spent versus the sonic improvements diminish.
However thanks to this forum I found that the point doesn't have to pass the price tag of an ADA Mach IV "B". I followed the ADA "Wow" thread, and messaged Joel and Jeff to ask their comments about the unit. I wanted to pull the trigger but was hesitant about starting the "equipment chase". I decided to give ADA a call and spoke to Tom McCarthy. After speaking with him he said that it is a no risk proposition as they give you a 30 day test drive.
I received the unit in about two weeks. This thing kicked ass from the moment I plugged it in. The detail and the impact is amazing. The Meridian had a nice ambiance to it but lacked detail. Also the bass was not tight and there was no slam. This by the way is with 4 Mark Seaton Submersives, Aerial 20T speakers and calibrated with a QSC 322.
I put on Master and Commander and felt my clothes move with the canon scenes. My wife said things vibrated upstairs in the family room. The detail was excellent and the bass was tight with a lot of impact. I was ecstatic.
I next put some two channel music and felt the same way here as I did for movies. Better bass and more detail.
I kept the Mach IV hooked up for about 10 days I then reconnected the Meridian again just to make sure before selling it. I didn't have to get past one song and one movie chapter to have my opinion of the Mach IV reinforced. My wife listened and she had the same opinion as I did. (Of course she thinks the Meridian was $1000 and the ADA was $500).
With regards to ADA themselves, they seem to be responsive.
I just wanted to share my experience with you.

. There is no question that in digital space, advances are fast and furious. A new PC is most definitely faster and more capable than one that is four years old. But analog reproduction? I am not so sure.
