By mixed I meant some think it's great, and other think it's just adequate (specifically with the LCD2)... lots of comments suggesting both. Finally just got mine in yesterday and I can see what both sides are talking about. Compared to my concerto there are quite a few differences, some good, some just... well adequate. Overall though I must say this is by far the best portable amp I've owned - Below are just my prelimary thoughts one the Hifi-M8 vs Meier Concerto with the LCD2.2...
Fuller sound - The concerto I always thought was a fairly bright amp. When I read all the comments about the LCD2 having the best bass people have heard, I never got it. The M8 brings it a step closer. Sound is nice and full, very good low end extension and a bit more laid back overall sound than the concerto. The low end may not match up to the gleaming reviews I've read of these cans, but since it's quite noticeably better than the Concerto, I'm pretty happy.
While the sound is fuller, it comes at a price of loss of soundstage and a tiny bit less detail. The detail piece is almost minute in difference really, but the soundstage difference is readily apparent. But overall I do prefer the sound package the M8 brings to the LCD.
Volume: While listening to anything other than classical, the gain is fine on the M8. However once you get into the quieter classical recordings, that volume knob is pegged. While seeing what others typically place their volume knob at (mine is higher comparatively most of the time than what I see others posting... I like it loud baby) that pegged level is probably "adequate" for most... but I do find myself wishing there was more. Now this experience also came with the concerto, but it just comes a bit sooner on the M8.
And the last piece is probably my fault. I ordered the RSA version as I have cables terminated for it with my IEMs... but this was my first time trying an RSA cable with the LCD2 and it doesn't really bring good results. I think the connector surface area is just too small to deliver the amount of current these things need. Will contact Todd later and see if he's able to work with me to swap for the 4-pin XLR version and I'll just make an adapter for my iems... otherwise single ended is working well enough with the LCD-2.
