What is the best THX amp available for a good price. It will be used for a theater room. I currently use all Denon products I have a 4308ci and a 2808ci. I have no need for multiple zones or any other extras in this room. The 1st Denon product offering THXultra2 is the 5308ci. But like I said I don't need the extras for this room. I'm looking to find something with comparable sound. Here are the speakers I'm using.

Klipsch THX

I'm only looking for advice on a THX amp. Not on why did I go with these speakers. I know there are many Klipsch haters.

I'm not sure why you feel as if you need a THX certified receiver, but take a look at the onkyo TX-SR805.

The lowest price Audio video receiver (not to be confused with an "amp" which is a seperate device that only powers speakers) that features THX Ultra II standards and post processing is the Onkyo TX-SR805, which you can get for around $700 in some places. It is a very new receiver, with a lot of nice new features.:) It's power is unrivaled at it's price.

Those speakers he is using need power behind them, regardless of their efficiency. They are load bearing at certain frequencies. You beat me on the click it seems, the Onkyo is a safe bet.:)

I'm new proud owner of Onkyo tx-sr805, and I can't say enough about how great it is, however judging from 10k budget you invested in speaker system I'd say go with top of line receiver :)

p.s: Looks like all Klipsch THX speakers have high sensibility (95-96) and imho there is no need to look for 200w per channel amps :)

I'd pick Onkyo TX-SR875 just for slightly more power than 805 and better video processor (Reon) = 1080p upscaling.

p.s.s: Both 805 and 875 are Ultra TXH 2 certified

Do you have a link to an impedance graph test of those speakers? I'd be curious.
Sorry, I don't. I apologize, I was making a generalization about Klipsch. Higher end Klipsch tend to have fluctuant impedance, that doesn't mean these ones will be.

That said, I don't think the power difference between the TX-SR805 and TX-SR875 is even a factor (I heard from another poster that the TX-SR805 tested better on the bench than the TX-SR875). The scaler, IMO, pointless. By saving money on the receiver you can afford to get a Blu-ray player which scalers DVDs to HD resolution, and also plays real HD content on Blu-ray discs. In my most humblest opinion, the TX-SR875 is pointless.

sooo considering that he spent 10k on speakers, most home theater guys rule of thumb is to spend between 30-40% percent of what your speakers cost on a amp/reciver... thats 3000-4000... you guys are recommending 1000 dollar recievers..shouldnt you be considering something a little bit higher.. maybe even the onkyo 905? with an amp.. or even separates

Not unless he needs additional features, such as the scaler, extra zone features, or network capability. The TX-SR805 has very good specifications and measurements, and packs a wallop of power that contends with the likes of top flight models from other manufacturers. I don't think any of those features are worth the mega jump in price, do you?

you seem to be well informed and want to educate yourself(and help others), like most others including myself, but dont you think that a upgrade of the other components that make up the unit be worthwhile? Dacs being one, but build quality all around would be simple enough. If i spent 10k on my speakers id want the best quality unit that i could afford, can a 1k unit drive the speakers, yes, but would a 4k unit have improved sound, i would think so.

The build quality is very similar among the TX-SR805, TX-SR875, TX-NR905. The power is very similar as well. The features aren't overwhelmingly different, nor are the DACs. I don't believe the TX-NR905 will sound much if any better with home theater speakers such as the Klipsch Ultra system. If more power is needed, there is Emotiva.:D

my fault, i wasnt limiting it to onks and emotiva, sorry i should have been more clear.

hey if he gets an 805 then it can double as a hot plate for cooking pancakes, eggs and grilled cheese :D

hehe, I can confirm it :)

On other hard 30-40% on amp of speaker cost, Denon AVR-5308CI might your choice :cool:, but my 2c the difference in sound quality/sound pressure levels would be minimal/non-existing between this one and Tx-Sr805 :D

Why would a company sell something that gets that hot?
It must take a toll on the life of the product.

heat is inherent in pretty much all types of amplification isn't it. I've never seen an amp that doesn't heat up when it'd driving a load. Some just heat up more than others. Different designs and of course operating parameters can lead to differences in heat production. Also, everyone keeps saying the Onkyo runs hot. Has anyone turned of the RIHD to see if that makes a difference? One guy at AVS mentioned that the HDMI control scheme causes the 805 to consume nearly 70 watts at standby. That figure should drop down to something more inconsequential with that function turned off.

ok, im all for seeing the theoritics on this with the onk, dont doubt it, but show me. and if the unit needs to be redesigned to make it all of its features to work without fault, im all for that also.
