mbqaurt QAA series amps Subjective only sorry
some guy over at eca wanted some info on these so I posted this
in case some of you were interested also
I have the QAA4250 (4x250) and the QAA2500 (2x500)
-----------------------------------
welp Ill try
ive owned a US Amps 5600x and a zapco studio --never the other stuff you mentioned
its better to me than both of those, albeit extremely current hungry (try 150A for the 4x250, and 200A fuses for the 2x500) so im currently alternator hunting
and thats not saying those two amps are great as they are!!!, but for me right now im keeping the Qlines
the ground floor is as low as all the other amps I have used (PG, audison, zapco, RF power, us amps and soundstream reference/rubicon and the list goes on)
hmm sweet footprint, very nice power supplies--quad mono on the 4 channel and dual mono on the 2 channel just really adds nice flexibilty and IMO a rather clean sound ,
extremly well built boards (much thicker than the average and even upper echelon amps--double sided)
heres a pic of the internals of my 4 channel

didnt open up the 2 channel yet
each one can do full power per channel into 4 ohm or 2 ohm, but thats limits the bridging potential and mono sub use to only the rear channels only on the QAA4250
it really adds flexibilty as the amp doesnt draww any more current or lose any (subjective) damping control at the lower ohm rating
so I can d2, or d4 subs, etc etc
and without the pops/clicks,and small percentage of failure rates of the RAA series\
as I have bumped mine rather hard in the heat and they have yet to thermal on me. and I have had no need to add the inline resistors some of the RAA amps require do to the pop/click
id say they are clean, no apparent hiss, or other background. the elctronic crossovers, and gains are very ncie and usefull IMO, almost like the digital processor on the new kicker lines
altough I use a h701
the crossovers/gains all can be bypassed together or seperate. so of course thats adds to the clarity of the amp
downfall it does have two fans , although they are quiet, EXTREMELY expensive, not sure of warranty due to mquarts/rf issues??
not sure if that was resolved
not sure what sound I call it as its really hard to compare since they are just soo much more powerful than any other amps I have used.. Id imagine just by listening and the destruction of some drivers lol, that the 4 cahnnel is easily outputiint 260-270x4 and the 2x500 Id put at 2x600 maybe
so as you probably know most auditory, subjective views on amps tend to be dictated by power output
there are some staging, control, bass, midrange difference due to amps, but these are up there with the best Ive used ( the Rf power, and lrx audison)
but in saying that, some here will even say those amps suck lol
but thats all subjective, one day Ill get them benched , but after buying them cash is rather low lol
I wouldnt have even considered them since no one uses them and they are costly, but in my tight space they were neccesary , am IM VERY glad I made the plunge
and they are rare since only certain dealers were ever shipped them, then the whole rf/mbqaurt battle hit the fan.. so you see some used, or even new on ebay, but those are dealers that got preorders, and if it from AZ --im pretty sure that seller has some insider connects as that is where the new mbqaurt/illusion audio distribution hub is located for the US
sow ho knwos if they will ever be in "stores" per say. ive never seen one here local
would I pay retail, NO--but I feel that about any amp or epectronic part. but I will say if I was ever to spend a grand ona amp the 4 channel would be it
these are probably keepers (especially if I can snag another 4 channel one day), meaning they wont be sold in 3-5 months like most of my amps
hope this helps
