UPA-200

Post by hemster on Jun 28, 2012 18:34:16 GMT -5
I looked up the specs on my UPA-2 and they are as below: 125 Watts into 8 Ohms (0.04%THD) 225 Watts into 4 Ohms (0.04%THD) 225?? I thought 185wpc on 4 ohms? I took the above figures from the manual.

The manual that I just downloaded matches the paper manual I have. 185 for everything except the UPA-1. Not that it matters really

I gotta say I'm a little concerned about the 13db less S/N at 1 watt compared to the UPA-2. 80 seems a bit low. Hopefully it's a typo. Am I missing something here?

Based on the specs, it would seem that the UPA-200 is a bit better performer than the UPA-2. Heat sinks vs. fans is irrelevant if both are equally efficient at dissipating heat.

Does anyone know the damping factor of UPA-2? This UPA-200 has good figures in it.

Agent 007, it's 185wpc@4ohms. Impressive job! I certainly didn't expect a better power rating on this one or even close to the original UPA-2. A pity about the SNR at 80 and that is A-weighted. The UPA-2 was not A-weighted which usually means there's some difference in the UPA-2's favor.
Since the UPA-500 is rated so well in SNR, I actually wonder if emotiva got too conservative with the UPA-200's SNR @ 1 watt. I actually think there's a chance the SNR @ 1 watt is better than 80 and just conservatively reported.
But overall a decently solid job all around emotiva. AND THANK YOU FOR THE PROPER RATINGS! That's how a product should be released and emo didn't let us down with that. It's an amp that people would want to buy and considerably more appealing than the UPA-500 in some areas for the 2 channel crowd. Now that the power specs are around the same, I'm very interested to see what they do with the XPA-200.

I don't know that I would say "better". Based on posted specs, it's irrelevant amount of power difference vs worse SNR at typical listening volumes. Emotiva's initial posted specs aren't known for accuracy right off the bat though. Once they get the test data posted it will be easier to judge.

Despite all the debate, I'm willing to wager that nobody can tell the difference between the UPA-2 and the UPA-200 in listening sessions. (There, I said it! )

I could care less about the power. 80db vs 93db S/N at 1 watt, where you spend most of your time.
Other than that, everything looks great.

The idea behind why UPA-2 got discontinued due to cost to produce and UPA-200 cost less to produce hence less material inside and replace by fans instead.

Better performer when it has 13db less S/N at 1 watt? Do you think that the lower gain has something to do with that? Look at the power rating into 4 ohms and the meaningless difference in SNR

Been following everyone's responses. I've had a gander at the product page and the UPA-200 looks pretty good. Honestly, the only thing that concerns me is the SNR figures.
I'll pose this question: what was the MSRP of the UPA-2?
Remember that these new UPA-xxx amps bring more separation between the X-Series and Ultra Series. In my opinion, these will be fantastic amps for the value-conscious enthusiast. We still have the XPA-100/200 forthcoming, and these will be a better comparison with the old UPA-1/2.
The hyperlink for the manual isn't available yet, but I'm very interested in reading that too.
Well done, Emotiva!

It's an inch and a half less in depth too better for space challenged installations. While I love the lack of fans in all of my emo gear bar the mini-x's (which I can honestly say I have never heard come on) I would love to hear the feedback on these new low end fan assisted cooling amps when the going gets tough and the spl's get up there....maybe if you play them loud enough to have the fans start up you won't be able to hear them over the music anyway

The UPA-200 should run much cooler than the UPA-2 as it seems more efficient. The fan should only activate with extreme use. If they are used with bookshelves or sensitive fullrangers, the fans might never get activated before the owner gets deaf

The fan in my 50 watt per channel (and smaller case) Mini-X doesn't turn on until I get into the 95-100db range for a few minutes. If I stay below that, then it never comes on. Even when it does turn on, I can't hear it outside 4' or so. Very quiet fan. I would assume the UPA-200 would be similar in quietness, and it probably won't turn on as often as the Mini does.
Also...jam, how is a difference of 13db SNR at 1 watt "meaningless"? That seems like a big difference to me.
