‘sonically as good as KR300B’

Posted adminPosted in - 300B all types, Reviews by Tube Model

Grant Fidelity provided a pair of sample Premium Grade A 300B-Z to TNT-Audio.com. Reviewer Geoff Husband says:

“If you are looking for a more even performance then the three candidates are the KR’s, the Shuguang and WE re-issues. The latter are very expensive, and to my mind offer nothing over the other two. The Shuguang and KR sound very similar, but the Shuguang build quality is inferior to the KR’s. The decision then comes down to availability and price – the KR’s are more expensive but beautifully made, but not always available. The Shuguang on the other hand are less well made, but at least as good sonically and, depending on market, cheaper.”

‘these are the most closely matched tubes I have ever bought’

Just recieved two pairs of CV181-Z ‘A’ Tubes from Grant Fidelity. They came in nice boxes, way over packed, and quick. I then tested them on my own Amplitrex 1000 tube tester, and, folks, these are the most closely matched tubes I have ever bought.

‘fully Shuguang-ed Mac’

Posted adminPosted in - 12AT7-T/TII, Reviews by Tube Model

by customer Atom shop:

I’ve been familiar with the Chinese Shuguang brand of tubes for some time. I’ve got a very rare collection of the original nickel-plate 7025 Select Silver Series which went out of production long ago. Bellari used these in their early VP129 phono preamps. McIntosh has used the comparable grey-plate 12AX7 version in their gear. (my own Mac’s stock tubes)

A while back I upgraded my Mac 275 outputs to the Shuguang KT-88 Black Bottle series. THAT was no insignifigant improvement! What a gorgeous aural sensation.

Now come the Shuguang Psvane Reference Series. I got a pair of nicely-boxed 12Ax7’s to try between my Mac C2300 and same 275. No matter where I put them the result was another several notches higher in performance. 

Holy Freakin’ Crapolla! The short rewiew: greatly improved dynamics, wider and deeper soundstage, increased air and space in the upper octaves, more slam in the bottom and just plain better resolution in harmonic detail overall from top to bottom. If ‘it’ is there, you here it better. If ‘it’ doesn’t exist, there’s no filler added to color the sound. 

I used to cherish my NOS Telefunken ECC83’s in the Mac’s phono stage. Not anymore! This pair of Shuguang-ies have now moved in and made it THEIR home.  They might be a smidgeon noisier but that’s hardly heard with program. (My current favorites at the Mac outputs are a pair of NOS Tesla yellow-ink, frame-grid E83CC’s. A super match in performance characteristics with the Shuguang-ies.)

I’ve tried all types of tubes in my Macs and over time I’ve cultivated a select few which I rotate from time to time. Along with my eggs there’re days I like bacon; ham is always a tasty choice. Another option is sausage links. 

My tube collection gives me a lot of HIGH-fi possibilities from which to choose from to satisfy my aural tastes. At this point, though, the Shuguang gang could take over the neighborhood. I’m going to try their 12AT7’s as well.
