In Reply to: Re: Integrated Amp recommendations for ACI Sapphire 25th Ann Edition speakers posted by J North on April 16, 2003 at 21:46:51:
Just a heads-up on the Unicos. Mine stopped working after only three days (after waiting two months for it to arrive, I was not pleased). Unfortunately, my dealer did not have one to exchange, so I had to ship mine off for repair.I have been told by the repair shop that they have no idea when it might be fixed because they're waiting for parts from Italy before they will even look at it. And apparently they have several other units in-house with similar problems--some that have been there for over two months. The problem seems to be that the speaker leads are somehow shorting out the amplifier section in the amp (this is weird, especially because they supposedly have a built in protection circuit to avoid this). Also, many of the last batch of Unicos had bad remotes, too (they go through batteries like crazy). Maybe the sudden demand for this integrated has resulted in careless quality control at the factory?
Anyway, although my dealer has been very nice about it, and has promised that he'll try to get me another unit ASAP, I don't have a good feeling about this, at least for now.
Just thought I'd share this with potential Unico buyers. It's a wonderful sounding piece, but the QC seems to be questionable at this time.

Follow Ups:
I've had a Unico since last August with absolutely no problems. Hopefully yours will be fixed quickly and Unison Research will take steps to make sure this problem is not repeated. Reliability seems to be an issue with many brands but it is unfortunate that a unit fails after a very short period of use. Good luck for a speedy fix.
Sorry to hear about your prediciment.Our Unico has worked great so far (knock on its wooden remote).
I would be interested to hear more about the speaker lead shorting issue to make sure we can avoid it.
No issues with the remote and batteries have worked for several months now.
I hope yours returns in good health soon . . .
Thanks for the well wishes, J.I'm pretty disappointed in the whole thing, thus far. I have no idea how or why the speaker leads might have shorted the amp. The unit was working perfectly, and then not. I did unplug the sources prior to opening the cover to reset the remote, but I don't understand why this would have caused the problem. Also, as I mentioned before, even if I did accidentally short the leads, the amp is supposed to have circuit protection built in to prevent damage to the unit (they even give you instructions in the manual on how to switch the jumpers to bypass this protection).
Anyway, I hope you continue to have trouble-free enjoyment of yours. It sure sounds nice, doesn't it?
Jon
Yes, it sure does sound nice.I wanted tubes some where in the system and seperates were out of the question budget and space wise.
As previously mentioned, the Unico absolutley destroyed my NAD C370 in a direct comparison. I was hoping the NAD would hold its own as it is 33% of the cost of the Unico. No such luck.
I am suprised at the QC issues as the Unico is very very well built.
My hope it is an isolated batch or relatively easy fix.thanks for sharing . .
Man, that's a bummer. No wonder you haven't posted your opinion about the Unico. I too have been waiting impatiently for a Unico to arrive. I guess I better make sure my dealer has more than one in stock before I get one. I've been warned by a number of people that Unison Research's reliability is a bit iffy.
