Ah I'm in the same boat. Although given some effort and time, perhaps reading a schematic wouldn't be too hard? The SS is really appealing to me because it's a lot cheaper than the other DIY desktop amps. Hey random question, how would you compare your Mini3 to your XXS?

Mini3 bit bolder, but not as resolved in terms of treble compared to the XXS. XXS is a lot cleaner, but mini3 can be more fun.

Its specified minimum supply voltage is 10V, but we have only about that much after the battery is just freshly charged, and will drop to around 8V-8.5V over most of the operating life of the charge. The LM6172 is not rail-to-rail, it will give you no more than about 1.3Vrms output voltage swing into a mid-Z load (100 ohms) before clipping, and it gets worse into lower Zs. Contrast this to the AD8397, which will give you 3.2Vrms (mostly load invariant). With 10V supply voltage, the LM6172's maximum output current is about 25mA into 100 ohms (not specified at anything lower than that), whereas AD8397 can deliver up to 10x that (rated down to 25 ohms load). Given this, the LM6172 won't drive high-Z or low-Z headphones effectively in the Mini³. |
cool, thanks.

I'm absolutely bored as hell, and itching to build an amp.
I think I might tackle the hohodiy neomini digiamp when I can get the money. Anyone interested in a tutorial?
Or maybe I should just build it and post impressions

Yea, do a step by step tutorial like that jac guy did for the mini3, and post impressions!
Or you could just save up for the CTH..

At current exchange rate, the base CTH kit is $240AUD before shipping and other stuff like panels.........
Hey nsx! I just came across an awesome DIY project that looks quite achievable. Have you ever heard of the Nixie Tube clock? It has nothing to do with audio but it looks awesome nonetheless
Here's an example:
Nixie Tube Clock Kit For Z570M, Z573M, Z574M, ZM1080 - eBay Tubes Acoustics, Electronic Components, Electrical Test Equipment, Business Industrial. (end time 13-Apr-09 15:45:34 AEST)

I think I'll save the money I have to build an amp instead.
Jaycar amp is next on my list due to its low price, and it seems to have quiet a high ranking amongst DIYers.

Now hohodiy.com has gone, does anyone do full kits?
Otherwise I'll have to source most of the parts myself.
