First tour of Xin's SuperDual amp - Page 2

Headphone jack and 9 volt input jack (on the opposite side of the amp)

New discovery about the 9v in:
When plugged into the wall via the 9v regulated wall wart, the amp runs on external power with or without the battery. With the battery in, it also gets charged. Charge time is "overnight".

If that comes in at the price point that has been mentioned. I am betting Xin will be a BUSY man.

The price point is going to come in higher than the $99 that Xin was trying to work off of a few months ago (weeks ago?). He went with some upgraded parts in the production models and the cost is going to be near or equal to that of the SuperMicro. Xin also mentions that the improved cases contribute raised cost over the Mini/Micro lines.

Too bad, but then again I'd rather pay a bit more and get the quality.

My main goal in the SuperDual is to have it be good enough that I will not feel the urge to travel with my Emmeline XP-7 but not so good that I use it ALL the time due to the small size. I have a feeling Dr. Xin will have the Dual right in that zone....

So if it was too good it would make your XP-7 redundant ?

I guess that there is a slim (quite slim) chance that the XP-7 redundant, but that would then mean that I would not need it and could sell it w/o having an upgrade path in mind. And we know that does not happen here at head-fi.

That being said, I am pencilling these amps in for different uses and think they will be a nice complement to each other. My MINT and SuperMini will probably end up being redundant, though.

$99 would have been a very attractive price point, but I guess if the sweet spot for price/performance (in terms of parts to use) lies slightly higher, then that's what we've got to live with.

It is potentially a killer combination relative to the XP-7:

1/ much smaller and therefore feasable to carry around with you
2/ much cheaper

Given that the XP-7 comes really approaches the quality of the Emmeline HR-2 (especially if you upgrade the opamp), it's hard to say that they would be redundant in quality. They might be redundant in usage, if you had the XP-7 strictly as a traveling amp.

However, as it is, XP-7 would make a great desktop amp even if one chooses to no longer use it as a travel amp.
