Capital AudioFest 2011

Driving a pair of Living Voice OBXRW speakers (from $11,000/pair depending on finish), this cute 20Wpc tube amp, from an American company run by an English ex-pat, produced a very appealing sound on a classic Louis Armstrong cut. The S20 comes with two mono power supplies, these using tube rectifiers and choke filters, and uses 300B tubes in push-pull. Price is quoted as being "from $12,750."
