KR Audio 300B BALLOON HP (HIGH PERFORMANCE)TUBES MATCHED PAIR NEVER USED!

** I'm a relatively new seller at Audiogon, but older on eBay. Please check my feedback on eBay, under the same user ID: ultima700 **

From my collection of fine 300B tubes comes this matched pair of KR AUDIO KR300B HP BALLOON tubes, in mint condition.

I bought this pair of KR AUDIO 300B HP BALLOON tubes during my last trip to United States, from the official US import and have never been used them.

Please note that these tubes are NOT the generic KR 300B Balloon tubes. Physically they differ from the conventional KR 300B Balloon tubes in the bases, that have been changed to a white ceramic base with gold pins and build quality vastly superior than the common version. Below, notes from the US importer:

*** "These are a High Performance version, only available in the USA. They are not sold anywhere else in the world. JPS Labs/Abyss Headphones, worked with KR Audio to improve upon their existing designs and further evolved these popular tube types for high-end audio amplifiers and high-end headphone use.
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 amplifier 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." ***

I tested the tubes in a friend's Audion 300B amplifier. They are perfectly matched and they sound fantastic, with a bass to die for, perfect midrange from vocals, silky highs...and fabulous sound stage!

You won't find these HP tubes at discounted prices anywhere! Only a few selected dealers carry these tubes at USD 1449.00; So please grab these tubes at this special price and buy them with confidence.
