Doctor, that's my another concern. Since I use this GG with Bruce's T8 OTL power amp. as a combo, alternating the SRPP output may affect the impedance amongs GG and T8. Am I right ?
-----------------
it does not matter. if you fix the GG problem, it will work well your T8 as well as another amp. |

Thanks for share.

| the problem is the use of SRPP as the output stage. SRPP behaviour is load impedance dependent. using it as an output stage will render the amp helpless. this is a fundamental change to the GG. using feedback as bruce did helps somewhat. but it is much better to completely get rid of the SRPP output stage. then you don't the feedback to help to fix a problem which shouldn't be to start with. |

Doctor,
U are welcome to tell the truth of this defect. For my current GG, I did only modiflied it's output gain by changing value of feedback resistors.
Anyway, looking forwards to hear from you soon.
Happy X'mas !! |

| if you don't mind me saying, there is a fundamental design problem with the GG. it would be much more cost effective to fix that first. |

引用鄭教授於國外網站上對VCap TFTF 在其 GG 既評論…'better material sounds better'，希望這對 VCap 也能順利發揮 GG 既潛能呢。

其實小弟個荷包一早已被清袋…
TFTF 及 OIMP 乃一齊購入，在參觀 G.T. 聽 27D 前已裝上現正在煲練。Vcap 在 GG 既表現肯定不及 27D (心中有數)，無計…

V-Cap 價值不菲喎！！
-------------------------
V-cap oil is quite reasonable. it is V cap teflon that kills your wallet^-^ |

Have you not already made one Matisse Ref. which kicked all the other Matisse, clone or genuine, out of the door? What differences will there be?

Vash,
I must apologize for this late welcome because my computer mon broke down at the worst timing last night. I had to rush off this morning, like a headless chicken, to get a new screen.
You are most wanted — the DIY wheels simply cannot turn smoothly without the chief mechanic on the spot. Don’t forget though, what we have here now is a test run to torture our server, to make sure everything is operational before we go public. All other DIY buddies have to wait until this test run is over. I am sorry they have to wait, but we cannot make the perfect meal with too many cooks.
Anyway, on behalf of all folks of 1 peking road, let us give you a big hand!

As I may told that I am under a living without hifi till the coming New Years day. I did some tricks on upgrading my 1541dac and GG tube pre. that need almost 500 hours for continous burn-in.
