Blue Circle may have closed its doors but Angela-Gilbert Yeung is still at it making completely built from scratch audio components under his own name "Gilbert Yeung", here are a couple reviews of one of the newer preamps the C312.

I run QUARK Audio and I have been the official repair tech for Blue Circle audio components as well as the US modification center for some of the newer upgrades and updates such as the capacitor packs for the past year. As of this past week I have also become the US dealer for all of his offered equipment. Everything is completely made by hand with minimal connections in the signal path and minimal circuit boards. This coupled with the most robust power supplies you have ever seen, Gilbert Yeung components will give you a musical experience you wont soon forget, or want to leave. Since everything is made to order, anything is possible and just about any need or want can be accommodated.
