The Audio Space Reference 3.1 300B is a beautiful world Class 300B based integrated amplifier. It also offers an internal tube based phono stage.

The amp uses four 300B's, two 6SN7's and four 12AX7's. Transformers are all custom made for Audio Space. The Ref 3.1 produces 21 Class A watts and sounds a good bit louder than that is the real world. Wiring is point to point by hand and the amp runs Class-A Triode Push-Pull. It allows switching between different negative feedback levels to optimally match different systems. It can even be run as a separate power amp.

The amp received a full review in the Absolute Sound by Dick Olsher. Dick summed up with:

"It should be obvious by now that I'm wildly enthusiastic about this integrated amp. The Audio Space Reference 3.1 (300B) offers a path toward enlightenment of being one with the music. Outfitted with a vintage pair of 6SN7 or even inexpensive 7N7 triodes, its musical pleasures would be captivating at any price point. Considering its asking price, it earns my nomination for a Product of the Year award."
