Any Golden Tube product you purchase should be upgraded with superior parts. Once upgrade, Golden Tube amps are one of the best buys in high end audio. I have owned both the Cary SLM-100 and Golden Tube SE-40 amps. Although Cary makes great products, a modified Golden Tube amp is superior to Cary amps and cost much less. My one suggestion however is to consider the SE-40 monoblocks over the SE-200. The SE-200 is very rare and not much is know about it. Their are numerous modifiers of Golden Tube SE-40's. For all kinds of input and help, see the Golden tube forum at:
