B&K EX 4420 vs B&K EX 4420 reference

I know this is a slightly older thread but I'm going to respond since I like B&K products a great deal. Here is how it goes. The difference between the B&K EX4420 and the B&K Reference 4420 is the Reference is newer and puts out 225 watts per channel where as the EX4220 is an older amp and is rated 200 wpc. They share very similiar designs but strictly my opinion on sound quality, I would give the older EX4420 the final nod and thats the one I own.

I owned a B&K EX4420 at the same time as the Reference 4430(3 channel) and the EX4420 seemed to have a bit more punch and refinement due to it being biased more class A or because it was a 2 channel amp vs 3 channel.  Not sure the reason though but that is what I experienced.

Both the EX4420 and REF 4420 are probably 95% the same amp mainly cosmetic from what I can tell.

Willland your first sentence nailed it and reflects my opinion as well,  well put.

@phd,

Thanks for the kind words.  I miss the EX4420.  It served we well and was a great trade for a Revel B15 subwoofer that has been rock solid.
