For your consideration is the amazing Audio Space 300b integrated. Holographic 300b sound, amazing design. Lightly used trade-in.
TAS 194: 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.
