Angela Gilbert Yeung Amps

Yes  have owned his products ,very well thought out and built 

I had a a smaller watt amp.. And my new  speakers needed more 

Depending on price ,a verygood sounding dependable product.

Excellent products from a Designer that knows the craft well. 

I rarely comment about other Engineers - but these are wonderful products

Best wishes - Mark 

The pumps may fit my wife , a different approach .

I sold blue circle back in the 2000s ,I think he may make a custom unit if you request something special.

I'm interested in hearing from others as well.  I've been watching some of the videos and dudes work looks legit!

Excellent circuit designs, enormous power supplies and very well damped innards are his trademarks. I have been following him for years. An amazing individual.
