As with the traditional 300B, the KR Audio 300B HP Balloon tube adds that classic look of old with the modern sound of new. This latest High Performance (HP) version has been tweaked to offer unprecedented silent backgrounds and greater clarity, allowing for subtle details in the music never heard before. We feel this is the quietist 300B money can buy, with a unique sound and appearance unlike any other 300B on the market.
First thing you will notice is the bass definition. It’s taught, powerful, and goes deep, allowing you to hear the rumble of the drum skin without bloat. Mids are in proper proportion, not forward or hard, with excellent placement in the soundstage, and float above the bass along with a good dose of airy highs. In all a very well balanced presentation of frequencies and harmonics with the finest of 2 channel systems and headphones.
The beautiful glass balloon version is more difficult to produce, and the larger glass surface helps the tube run cooler and adds a bit more harmonic richness. It has similar specs as the standard 300B and is compatible with any 300B amplifier.
These are a High Performance version available only through The Evolution of Sound. Pricing is for a matched pair of tubes. Quad matched sets available upon request.
