I've owned a lot of gear, mostly very good stuff from good companies (ARC, Rowland, Bryston, Clayton, Magnepan, thiel, vandersteen, Harbeth, Accuphase and more).
The only Company that I feel loyal to is Blue Circle. Great products all through the line, terrific support. But what really differentiates them is the willingness to customize for the customer. No other Company that I'm aware of will make you a preamp, amp, dac, etc. with exactly the features you want. They build to order and if one of the existing models does'nt meet your needs, just specify what you want and Gilbert will build it.
