Yaqin Tube Buffer With 6J1 Tubes (Valves)

-

Just received my Yaqin tube buffer. My opinion is divided so far. The small buffer introduces a good amount of noise at higher volumes on my system. On their own, the Lepai amplifiers I use at this moment did not show any noise even at maximum volume. Since I installed the buffer between the pre-amp and amp, the noise level is remarkable. I have to limit the Lepai to half-power in order to get the noise level to an acceptable level. This being said and before I find a fix for the noise issue (if there is a fix), the Yaqin buffer is very interesting. I does add an exotic element to a system an provides very smooth sound and separation. The source material seems to matter a lot as to the effect of the buffer.

If I keep the Lepai TA2020A+ amplifier at lower levels and only use the pre-amps volume, the sound is excellent and very detailled as is channel and instrument separation.

The blue LED lighted logo adds an interesting touch.


I am still investigating this little device and will report later with more comments.

Revamping My Four (4) Large Advent Speakers Changing The Fabric On the Large Advent Speakers This year I decided to put my Advents back in full working order. I own four Original Large Advents. Two of them were in storage for over 2 years, the other two were functional in the living room. I started by cosmetics. Not only was the fabric stained and discoloured, the cats had a field day piercing little holes in them.... The result were speakers that had lost their mojo. So I decided it was time to change the old fabric on the speakers. Since I intended to restore all 4 speakers and stack them, I had to make them look good as well as making them fully functional. So, I bought fabric. I looked around and tried to find a fabric that would look good on vintage speakers. Of course this had to done without braking the bank, I could always change them again later. So, I purchased the least expensive, best looking fabric I could find. I found a good source in China . Other places asked ...

Akai EA-G40 Stereo Graphic Equalizer, 8 bands. Used it for a while, but my current set-up doesn't really require equalizing, also, equalizers tend to add more wiring than I like in a system... I run everything flat, what you hear is what you get... K.I.S.S (Keep it simple and stupid)!
