Yaqin CD-1 Tube Buffer

Use a tube buffer to give your system a warm and rich sound associated with tubes.
The CD-1 uses a dual triode (like two tubes in one) 6922 tube
Versatile placement: place between preamp/amp, CD player/amp or in tape loop
The CD-1 is the #1 best selling tube buffer on the market - Pacific has been selling these since 2005
Uses RCA jacks for input and output, 120V AC.
The Yaqin tube buffer is based on the 6DJ8 / 6922 tube and is guaranteed to add the magic of tubes to any system without adding any significant noise or distortion. The Yaqin tube output stage can be added to any system: perfect behind any digital player, in a tape monitor loop or between your preamp and amp. Turn your IPOD, CD or any other affordable digital player into the tube-hybrid player of your dreams. Add it between your amp and preamp or into a processor or tape loop and hear every single source component come to life in a spectacular way. Once in place, you will hear anadded level of richness, warmth and musicality previously attainable only with a tremendous investment in world-class tube gear. The Yaqin Tube Buffer Stage is the easiest way to upgrade your system.

What we like about the Yaqin is the twin triode 6DJ8/6922 tube where only one high quality tube is required. In this way, you can keep the stock tube, roll to more musical tube or keep 6DJ8 /6922 tubes and change them at will.

Is the two tube one better than the one tube one? Its got two tubes in it - its got to be better, right?

Not so fast kid-O.

The two tube buffer uses an obscure 6J1 tube. While this has NOS derivatives, the 6J1 is still not as well known as the 6922/6DJ8 tube that the one tube version uses. The one tube version casts a very musical sound stage. The two tube version was very bright and made the high end hard. Not to our liking.

The one tube version gently pushes the sound through the speakers in a way that makes music. It can smooth out just about any harsh CD player and add a tube quality without the expense of equipment replacement.
Heard around the water cooler:
Experiment with various 6DJ8s / 6922s to get the sound you like. We tried Amperex, Siemens etc and achieved surprising results.

From our stock, the Phillips 6922 is the most subtle as it gently softens the sound. The JJ Tesla is slightly more musical and this tube, we surmise, gives you the most bang for your buck. Most folks order the two tubes and experiment that way.
For the RIGHT tube, its Tube Righteousness !
