  •  FAQ
     Q: what is Class A ?
     A: Class A means that the power tube conducts the same amount of current all the time, whether idling or producing full power. Therefore, it will be high temperature from power MOS FET in normally. Class A is very inefficient with electricity but usually gives very low distortion. This is to decrease the distortion such as a high-end amplifier.
     Q: Can I change the 6DJ8/6922/6N11/12AU7/6N23P...... tube to improve the sound quality?
     A: The each one of 6DJ8/6922/ECC88 is fully suitable for replacement with much difference musical taste chose by owner, but it is not 100% improve the sound quality absolutely; some time it can change to the favorite sound by carefully chose; a precession selects and checking is most important. Never superstition to the high price tubes!!

     Q: I find a similar product with 3 bands EQ, does it better than your G2?

     A: By our sense, any tone control will be colorless the sound and distortion, so you cannot find any high-end device with a tone control; it also build in mid/low grade Hi Fi device except Marantz 7 / Cello Audio Palette.

                 What is different coming?
G2, it has grown up from old version Indeed Valve Class A Hybrid Headphone/Pre-Amplifier, we does not satisfy to let it improve only!
We have modified to generation II now, so that we call it
G2.
1/ Output signal also15 seconds delay when power on, it is important to reduce the ‘pop’ pulse, safe to your ear and speakers.
2/The thick of PCB increase to 1.8mm with carefully design grounding, the RF pollution and noise ratio also improved.
3/ There are ALPS signal selector, long life 10000times power switch, heavy duty I/O parts & switches to use.
4/ It is good news to ‘tube roll’ people, easy to change the tubes with switch (bias adjust is necessary), 6 series for 6DJ8/6922/ECC88/6N11/6N23P; 12 series for ECC82/12AU7/12AT7/6N4……also too many choose by owner right now.
5/Ultra large current Class A output design, it can drive the low impendence headphone in 12 Ohm loading; a very deep and powerful bass you will be hear !
6/ Audiophile Performance Design Absolutely! It can direct hook up to power amplifier such as Pre Amp to use; it will kill any pre amp with US$1000- price (may be higher)!!
         


 

"Dale" resistors is very high cost than other similar product, it working most stable in long life and also sounds…
• Precise pin pointing focus.
• Equal resistance (L/R) all the way.
• Deeper depth and sweeter vocal.
• Cleaner bass and sweeter treble.
• Sound image is much improved. Pin point image!!!

If you would like to take total care of your amp, resistors are the first one to be focused. Resistors are used more of any other components in an amp circuit, therefore each small impact can make a big difference in total.

OH MY GOD!!

How can it be? Why do expensive HP and pre amps have to be so big and so expensive when something so small and inexpensive out-perform many of them. Not that I've heard a lot of expensive amps but this is stunning IMHO. I'm listening to mp3 tracks out of my iPod that I am very familiar with and hearing things I've never heard before, particularly in the bass area.
I'm now going to feed it from my mod'd Beresford 7520 DAC and play some FLAC files from the PC - should be even better.
In terms of SVPP this has got to be my best buy by far.
More to follow.
Cheers,
Smug and Satisfied of Sheffield.

PS and yes, I like it, a lot!! davek    

had my G2 running for a couple of hrs with supplied E. Harmonix 6922 and PSU on loop before listening test.

First impression is, very nice, not creaming my pants yet, as the Brxxx and Mixxx are a tough act to follow.

Its giving me a very strong prior warning of incoming texts, and not quiet as strong on outgoing ones. No HISS at all, at anything other than insane listening levels, and NO HUM at any level.

The sound is very spacial, easy to place individual instruments, and nice detailed clean deep Bass, accurate smooth Mids and crisp top end. cymbals, violins etc are very nice.

Overall very nice and i am pleased with it, more time for it to settle, and then maybe some extra pairs of clean underwear will be required.

Will report back tonight with a days running on it.   17-3-2010 heliharris
