Gary never had problem with taking apart krell mono's ( up to the 600's), that pretty straight-forward operation. In which area did you feel JHL's did for you mids, or top?, or maybe you just preffered the JHL's pure and simple They are not lush or overly rich valve sounding, more transparent and liquid in stock form. did you spot if they were Gen II's? The B/c runs by far and away the best when Bridged, most dealers in the UK don't demonstrate this, although Mr Roberts has been known to do it right. They are also very picky with mains, that I would say is a area they (belcanto) needs to address, any piece of equipment that has such large gains due to power treatment and rfi mods, should be considered for redeveloping of its PSU array. It took 12 months and the odd mishap to finally nail come up a decent engineered psu, and trust me here, the surface has only just been stratched with PWM technology, the possibilities are quite limitless, and with more and more companies (mainstreamers too) investing in this, the R & D is being put in and the results are exciting to say the least. Still a way to go yet before its 'soul like', but the promises are starting to be forefilled. However at its price point (and above) when fed right, it will sing. Just most of the guys who sell them (in the UK), really have no idea how do use them to there full potenial, which is a shame. But hey thats hifi for yer!!!!!
