I just received my upa-1s yesterday and have hooked them up, replacing an old adcom power amp. They are powering my magnepan mg12s. Do they need a break in period to sound their best? At first listen they sound a little harsh compared to what I'm used to. I've listened to them using my Belles preamp and also using my cambridge-audio receiver as a preamp.
Hi maggieuser, i hope your right about break in time.I have the upa 2 right now and it sounds great.With the sale going on right now, i thought i would go for the upa1's.Everything i've heard about them have been positive.Should receive mine tomorrow.I hope after you get everything tweeked out they will smooth out for you.Thinking about getting some MMG'S for my upstairs.

My UPA-1's arrived yesterday and I am delighted Very warm, musical, and detailed More so than the NAD 2155's that they replaced Currently using an SAE Two P10 preamp (until the XDA-1 is available ) along with an ERC-1 and a pair of A/D/S L1290 speakers

I'd give them some time. I bought my UPA-1s second hand and noticed that their sound improved after I left the system run with FM material continually for five days. Part of that might have been additional breakin for the Magnepan MMGs.

I have let them run continually and have been spending alot of time listening. I do have to say they are sounding better. Changing my source also helped, as we all know, the better one piece of equipment is, the more it shows weakness in your other equipment. So far the soundstage these amps put out makes my system sound like I've got my surrounds turned on. I swear sounds are coming from beside and even almost behind me. The more I use them the better they sound.
Either I'm getting used to the sound or they definitely are smoothing out. They are certainly worth the price I paid for them. Someday I'll take them over to my friend's house and compare them to his Plinius amp.

How are the amps sounding now that they have aged some more? Did you ever perform that shoot out with your friend's amp? Do you still feel these amps are warm? What about raw power, are they robust and authoritative at only 200 watts per channel?
