I received my upgraded amp today too! I'm happy to report there is a significant improvement in sound quality, especially in treble part. Overall it's more detailed, more balanced than the pre-upgrade amp. The original amp is so bad (treble roll off) that I did not even bother to ship it with tracked delivery for upgrade :-)
A quick listen shows the upgraded amp is on par, if not better, than my Graham Slee Voyage. Finally I no longer need to drag an amp with my HM801 :-).
BTW: turn-around for UK customer is about 2 weeks (need to ship to China)
