I recently added the Anthem AVM30 to my HT to replace the Boston Acoustics AVP7 which replaced the 990 which replaced the Yammy 2500. I also added an Emotiva MPS-1 which replaced the BA A7200 which replaced the Outlaw 755 which replaced the Yammy's internal amps.
There was a large difference between the 2500 (when used as a pre/pro only) and the 990 in favor of the 990, a very slight difference I felt in favor of the AVP7 over the 990 (not surprising as they are both built on the same platform), and again a large difference between the AVM30 and the AVP7 favoring the AVM30. This shouldn't be all that surprising when the pricing of these units is examined except for the closeout pricing on the AVP7.
I am very happy with the AVM30 and am no longer even thinking about the audio, just enjoying it. My only upgrade in the area of the processor will be to have the AVM30 upgraded to an AVM50 when the upgrade is available...and when I can afford it...
ouch! I think I could actually live with the audio quality of the AVM30 for a long time. The Anthem has excellent sound and more extensive setup options than todays most complex receivers; to ME, this was the best of both worlds.
The MPS-1 is very open and sounds amazing. Channel separation is astounding! It is also a piece of art and truly glorious to look at. I have not tried hooking the Outlaw 755 I still have to the AVM30 yet but may try to do so before selling it to see how it fares as I have compared the 755 and the MPS-1 hooked to the same processor in my setup.
The AVM30/MPS-1 is the best sounding combination of gear I (stressing this is my opinion here) have heard in my HT thus far and I doubt I will ever hear anything better in my room as this was pushing my budget as it was. I'm stopping with this as I no longer feel I'm missing anything now...and if I still am I don't want to know about it...ignorance is bliss!
Of course I still have to figure out what I am going to power zones 2, 3, and 4 with
I wish more companies were still making two channel amps. The selection here has really died off in recent years. Maybe I should just use the 755 for two of these zones...I don't know but that seems like overkill to me.
I would be curious to hear your comparison of the Meridian gear to the 990 as I have of course heard excellent things about Meridian. Then again, that may just get me in trouble again.
If I was smart, I would avoid all these forums and enjoy what I have and not look back. I do enjoy comparing different gear though and replacing pieces from time to time. To me it's a part of the hobby of HT.
Peace!
