Now what is going on? This should be a major upgrade. We know there was a problem of stability and some oscillation problems. Stability problems were probably corrected on 27th tweak. As Xin is silent he must be in the tweak mood!
Goto do you know what is going on? This .01 % tweak still has its own problems needs optimization? Let us know!

FWIW, I have the 99% version I guess, and I have had no problems with it of any kind. Sounds great too!

The sad part is that Xin's a rocket scientist, which means he has a *Really* good calculator somewhere, and can easily start tacking on 0's after that "99."

"After the mid-afternoon 8/12/06 tweak, version IV is 99.000000000000125 perfect!"

You gotta love the guy, unless of course you're waiting on delivery...

Well I ordered mine today, I hope to get it by the end of September.

dr. xin is back! great news, he's finally done with the 100% and will be sending out amps real soon. check out his website for an update by him.

send it back?

My XIN Supermacro IV was shipped 7/28/06 minus the .005% tweak so am I correct in reading DR Xin's post today that I should send it back to make it 100% complete?

Cheers,
Robert

Thats right, I definetly would send it back or you will always wonder how it could sound.

I'm sure it's great anyway though.

on the fence

Howdee XIN IV owners,I'm on the fence about sending my XIN SuperMacro IV back to DR. Xin for the 0.005% tweak. not even sure if my ears could hear a difference.
How many folks who have their SMIV plan on sending theirs back? Mine shipped 7/28 with 99.99% of tweaks.

Cheers,
Robert

I would strongly advice you against that. You probably should wait for Xin to ship out all the July orders first before sending it back. Meanwhile just enjoy you 99.99% Supermacro, it's amazing even without the 1%, as in my case. . And keep in mind that this amp benefits a lot from burn-in.

Thanks,the devil on one shoulder sez send it back send it back! the angel on the other shoulder sez no be happy with 99.99% DR. Xin will take forever and you could be hit by a bus and not enjoy your last days on earth with a sweet portable tunes system.

I'll take your kind advice and wait.
Also a fellow head-fi-er who lives nearby just got a Larocco PR II that I'm DYING to compare my XIN with.

Cheers,
Robert

IMHO, it's really difficult to define whether it's 0.01% or 1% or 10%. From pure sound quality standpoint, it's much more than 0.01%, probably >10% ( seems like hyper as well) for those IV amps that are stable; for those not stable, it's more than 100%
post #148 of 3957
so in essence, its not really that the amps are 100% now, its just that xin was able to solve whatever problems he thought existed. of course there could be other problems he finds himself, by you, or some engineer that got their hands on it, of which there will be yet another tweak right?

another question, do you know if the boards on the amps are manufactured or does xin have to do it manually for each one? and do you know how long it takes for him to build one amp?
post #149 of 3957
yes, the perfection means he has solved all problems he thought of or encountered. nothing is perfect to headfiers, you know that Acutally, Xin's very easy to be satisfied in sound and I doubt he would have made his amp sound super without the feedbacks of his amp users. Whenever he claimed XXX sounds great to him, pls. keep this in mind

Xin made every amp himself and he once mentioned that it took him around 2 hours to make a Macro.

I don't plan to send mine back for quite a while, if ever, since I don't want to be without it, and he's certainly really backed up with work currently.
