I've been going crazy, trying to decide if I should run my Rti A9 (modified with sonic craft capacitors) on Xpa 1 gen 1 or gen 2.
I'm not sure if my rtia9 will eat up the 60 watts of class A power easily, in which gen 2 doesn't provide much benefit to me over gen 1.
I am currently xpa 5 and i feel it's not quite enough. 2 days ago, instead of running the xpa-5 on 5 channels, i only ran it on 3.
It was huge difference! The sounds was clearer and more crisp. Even my dad *who's not an audiophile* realize the difference without me telling him the change.
I really would like to take advantage of the sale going on right now, but I'm stressed if i should wait for the gen 2.
Assuming the gen 2 is $1000 each. If i grab a pair, that's $400 savings. either way I'd still get a 5 year warranty from emotiva.
I'm currently running:
Yamaha- RX-v3900 Rti a9 x4 (all modded) (but i'll get rid of the surround pair and replace them with fxi a6 soon) Csi A6 xpa-5
any ideas? much appreciated!

I can tell you that you'll wont be disapointed with the gen 1 but if you wait for the gen 2 and the 60w class A, I'm pretty sure that it will not disapointing to. Maybe exept for the extra of heating but the winter is coming.

Yeah, I'm sure i'll be happy either way. both will be awesome amps!
my question is if my speakers aren't efficient, then even at low volumes it will use more than 60 watts, which means I will not get the benefit of the class A action?
Sometimes I'll listen to music while doing chores, but most of the time, it's going to be use in theater mode. My living room is about 400 feet with open door ways.

60 watts is a lot of power, even if your speakers are not very efficient you will reach 60 watts at high volume.

For exemple: If you have a loudspeaker of 86dB at 1w/1m at 64 watts it will produce 104dB at 1m in theory.

Which in theory it will still be over 90db (pretty loud) at 10 feet away....

Your Rti A9 are listed at 90dB 1w/1m, so they should produce 108dB at 64w/1m

How loud do you normally listen ? I use an xpr 2 for my a9's and have no problem getting the led meters dancing. Do you use them full range or cross them over at 80-100 hz ? How far away do you sit ?

With the Polk RTiA series I would say save the $400-$600 and get the Gen 1's, heck even a XPA-2 would be great for those towers, btw how big is your room and how loud do you go, I have yet to hear from anyone that the XPA-5 sounds strained when running all 5 speakers, I never even found my UPA-500 to sound strained while watching movies at loud volumes.
Is your XPA-5 plugged straight into the wall or on a surge bar, I could maybe see that happening if it being limited of it's incoming power/current needs.

i use to own a pair of RTi10 and they are just below the one's you have (RTi - RTiA series) and i had them connected to my XPA-5 and it was plenty of power, tons of power. you won't be able to handle sustained listening periods with your speakers on an XPA-5 at a loud volume unless your 20' away or something. sometimes i believe that what we think we want isn't anywhere near what it is that we actually need and most of the time it's between the two and it's often influenced by what we think people will think of our choices. i'm not saying you shouldn't get either of thos amps, i'm saying, i think you will never really challenge those amps unless your playing those speakers, full range and at super high volumes with a source that has tons and tons of low end all the time. of course, if you have the money, and it's burning a hole in your pocket, emotiva will be glad to take your money. best of luck, keep us posted on what you eventually go with, why and how you like the sound your getting with it.

it will read around -35db to -25db. usually in this range on the receiver 104 db in room is LOUD. Probably around 0db to +5db on your reciever. At normal listening levels like you said (-35db to -25db) you probably wouldn't even get the XPA-1 gen1 out of class A very often. (around 10 watts) Also who knows when the gen 2's will be out? They said to look for them just before Christmas, but there is no guarantee that they will hit that deadline. Just some things to consider.

Just a general suggestion - if you are wondering about sound levels I highly suggest getting a db meter.
If you have a smart phone - there are a few apps too. Even if they're off by a couple db (the iphone app SPL Meter by Studio Six Digital seems pretty accurate) - you'll learn a great deal about what listening volumes you like.
In my experience no amount of charts can really translate to identifying how loud you like your music.

In my experience no amount of charts can really translate to identifying how loud you like your music. couldn't agree more I was so surprised to see what levels I normally listen at but it can jump 12-15 db in a fraction of a second so to me having the power on reserve to make those jumps is a must.

I have the a9's. I have ran them off an xpa3 xpa5 upa2 and xpa1's the xpa1's gave them the power they needed and they never sounded better. But I think an xpa2 would do the trick. I now use a sherbourn pa7-350 and it is a big step up in dynamics and punch than even the xpa5 that it replaced. I would not worry about the gen1 or 2. Save the money and get the gen1 xpa1s. You will love how they come to life. They are 90db sensitivity but they do love power and will take what you throw at them

sounds good, getting gen 1 to save 400 is a big factor.
i was just assuming if there's a christmas sale, then there's probably a discount for the gen 2 for 100 each.
so the difference will be 200 dollars instead of 400.
why i'm assuming this? because the gen 2 xpa-2's also go 100 dollars knocked off their price, even when they are the latest product.

As an owner of the rtia9 and xpa1's the xpa1's led meters would go into the red during during some scenes I sure hope that's more than 10 watts or the LEDs are totally pointless.

Don't forget that the price of the XPA-1 Gen 2's will prob be $100 more than the regular price of the Gen 1's as well, botht he XPA-5 and XPA-2 increased by $100 from the Gen 1 price, so I would have to guess they will be something like $999 regular $1099.
