Board well manufacture with easy to follow guides. Only problem I had was my heatsink made getting to resistors difficult when setting the bias. The bias can slide good 15% as it heats up so listen to the guides when they say to set after the lid on the case has been on for awhile and to start with lower setting than final when first use.

I first listened to it with an old DVD as a source with suspension speakers and I was so disappointed. It was dull and liveless. I nearly stopped working on it. I then plugged it to my TV output and I heard much better sound. I then tried it with my usual source and a 39 year old Pass designed Threshold Amp pushing some electrostatic speakers. I was sitting with my jaw open listening. The rest of the night digging out music. Just when I was done my wife came in and started pulling out her music. It was wonderful and far better than an homemade preamp and 4 decade old amp have any right to sound like. I really can't find anything bad to say about it's sound. If it doesn't sound good in your system you need better other stuff!

Very nicely engineered!

For the price the boards are OK. I have purchased several different ones and have never had any problems at all and the shipping was good on all.I wouldn't be afraid to buy from them again like Iam today.
