I've been lurking for a while, and on the strength of the excellent advice offered by HeadphoneAddict, AMB, Tangent, PPL and others, I've bought a Penguin Caffeine, Mini3 and a PIMETA, as well as built my first LOD (a temporary one at least). The Mini3 and PIMETA have both been bought as parts shipped from the USA and built. They both sound great. Unfortunately the Penguin amp still hasn't turned up.
I bought mine on the 18th July, and it says it was shipped on the 8th August and then AGAIN on the 22nd August. I've sent 3 emails and never had a response. I don't mind waiting, it's just the lack of any communication that worries/frustrates me. Is it possible that it was shipped twice and BOTH went missing??
I suppose if there's no delivery and no communication, then I'll just have to put it down to experience and forget about it.
The Mini3 and PIMETA sound fantastic though. And the Mini3 was a really nice experience to build. The PIMETA was a little harder, with all the "variables" in part choices, but I've got the measure of it now and so I'm putting together the BOM for the parts for a PPA and Battery board.
