Lets be fair here, the Burson does very well. It provides a good sound and achieves a very good level of resolution. I don't care too much about what construction method was used. A bit like the super cheap Chinese amp Walpurgis bought for about £30 all in.
The sound quality is very good for the money, I'm not saying it's on a par with your amps or my own Krell but neither of those cost £380 did they!!!
