I use this amp for over 4 years without having any concern on it.
The advantages of this amp is that you can do work without any problem under 2Home, even in bridged 4Home are still low distortion and the power is really at the same appointment on bass.
The most uncomfortable with this amp and all those in the pro series of crest (4601,4801,6001,7001 etc) that they are very heavy, that it is normal for the amps of a previous generation (but work much better than some now).
I compare the 4801 crown with mt1200 home and a home chevin.Le mt1200 A1000 is better than the 4801 in the most comprehensive bass boxes, but I find mt1200 less defined than the 4801 or the A1000 in medium acute and I preferred the 4801 because I think it comes out as well as the A1000 in the medium acute, but the 4801 can be used in 2ohm and be bridged by 4Home that the A1000 does not.
Nine is a heavy investment, much more accesible to occation, but product quality is there and it pays.
I do it again if that choice again, I recommend using this amp for small speaker pro as home PS10 Nexo, mtd112 home Acoustics, DS12 apg last home in that range there.
