I am glad to be selling the Audio Space Electronics. These components offer tremendous value and every review talks of their great sound and build quality for the money.

The Reference 3.1 (KT88) is just one example. This 48 watts per channel KT-88 integrated tube beauty competes with the likes of CJ and ARC at a fraction of their prices. Build quality is superb and the cosmetics are gorgeous. The 3.1 also puts out 26 watts in triode mode and has a nice moving magnet tube phono stage. The transformers are all custom hand wound. Wiring is all done point to point by hand. Circuity is unique to Audio Space and not simple old designs in a nice chassis. You can also fine tune the sonics by adjusting the amount of negative feedback. The meter makes biasing it simple.

Affordable Audio summed up their review with:
"In a world of big buck wires and six-figure speakers, the Ref 3.1 defies logic. How can something this good be built and delivered at this price? What we have here is affordable audio at its very best; highly recommended"

Ultra High Fidelity summed up by saying that the Ref 3.1 (KT88) has "a level of refinement that goes way beyond its price point"
