Moscode 401 HR vs. 402 au vs. Butler TBD 2250

Caution there is a problem with the Butler's when they are used as mono blocks in mono mode with 4-6 ohm speakers. You will get limited bass.

Thanks Clio09 for the reply. The Butler is less than half the price of the Moscode and its possible George may be asking a little too much for the 402au. One could have 2 x Butler TBD2250 800 watt per channel (in mono mode) for less than the price of a single 402au.

Would be interested to hear from other Butler and Moscode owners.

Another option is Space Tech Lab from Canada

I don't know if it's a marketing gimmick or not, but as good as the 401HR is, the 401au is better IMO.

I have heard the 401HR in comparison to the Butler 2250 and to me it's a toss up. They both are very nice amps. I think the Moscode has a slight edge in tonal balance and overall presentation, especially sound staging and high end frequency reproduction. However, if you need a little extra power the Butler might be the better choice.
