Just wanted to say how much I am enjoying the sound of my sse. I bought the small fostex kits from madisound to use with it. I am listening in nearfield, about 3 feet away in triode mode with no feedback. I am amazed with how the midrange sounds! I am enjoying my music collection more than I ever have. Especially vocals and acoustic guitar. Wow! Sounds life like! I've been wanting to build a tube amp for years and I finally did it. Wish I had done it sooner. This amp flat out embarrasses my ss receiver especially with vinyl. Many thanks to George Anderson for designing this amp and making it available to us. Sometime in the future I will be building a simple pp and I have no doubt I will love that amp, too!
