Question: I have an Onkyo TXNR 818 set up 7.2, with polk monitor 75t as fronts-  Would this amp 1) work with 818 2) power them better for Music and HT? Thx
Document: I read a lot of reviews in my pursuit of a nice power amplifier. Purchased this amp looking to get more out of my front speakers of my 7.1 stereo. Sound is better for sure. Unfortunately the toggle is not compatible with Onkyo receivers. But that's ok. Well worth it to turn the amp on manually.
I have a 7.2 home theater. I have an onkyo tx-nr809 a/v running it all so I thought I would use this amp to run my front speakers. I have axiom speakers. Amp is very well made and for 300 bucks was a great deal so I pulled the trigger on it and am very happy. all their stuff is on sale right now so if your thinking about emotive just do it they make a great product.
For well under $500 you will not find many amplifiers designed for the aspiring audiophile. When combined with its matching preamp. it works well with music and as the heart of a two channel home theater system. Seems to cover bass to treble without leaving me feel something is missing or not enough juice to drive speakers. For the price I highly recommend and matches well with Polk RTI A1 speakers or LSA 1 speakers.
I truly believe that Emotive makes the best external amplifiers on the market for the money. I was skeptical because of the price, but after doing countless hours of research I figured I would give it a shot. I am so glad I did. I have this powering a pair of Monitor Audio RX8 towers at a 4 ohm load..... and it does it so effortlessly. The signal is coming from a Marantz receiver and together the sound quality is better than I expected and I had high expectations.
I fully recommend this amp for people with a listening space of 350-400 sq.ft. and 2-1/2 to 3 way speakers.
The amp will handle 4 ohm loads, but I am only running some Bose 201's at 8 ohm to "preview" what I need to do about upgrading the speakers. Comes in black finish with chrome trim on the ends (you can order black trim through Emotiva). Rack ears are available if you choose to mount yours that way. I have found nothing that I have an issue with after one week. Although this is a stereo amp, you can run 2.1.
I'm comparing the UPA-200 as an amp & against another amp & against 2 amps mono-block style using1 amp for the left chnl & 1 for the right. IMHO the Emotiva amp is indistinguishable from the other amps costing much more.Now there will be a lot of comments about bass mid treble extension dynamics etc. & everyone has a valuable opinion! !I just do not think that the average  person & ?Audiophile can go wrong at this price range.
This amp joined my Rotel pre amplifier, and the PURE doc for my living room stereo.I am a big audiophil, and have a dedicated audio room with much more expensive audio gear, so i did not expect mcuh to begin with. this amplifier surprised me with its imaging, lower end punch and overall presentation. this is even better considering the cheap DAC provided by PURE and the MP3 music i listen to through my ipad. overall rating ; very good bang for the buck. recommended.
but it sounds great too. Seriously, I bought a new stylus for my turntable that hadn't been used since 1982 so I could spin a couple of the 1,200 vinyl platters I've been hanging on to, and here I am. I bought this with the Emotiva USP-1 pre-amp. They work and sound great together. I visited a couple of high end stores and the Emotiva pair was had for just of the price of a higher end pre-amp.
In fact, it sings beautiful mids and delivers extraordinary bass. I have tried it with an Arcam 280 as preamp, a NuForce UDAC2 and with a NAD 356 working also as pre. I tried it with different speakers also, it was great with bookshelfs and towers, namely Monitor Audios Br2s, Mordaunt Short Carnival 6's and Mordaunt Short's 2 and 6.
Answer: Your receiver has plenty of power to drive the Polk speakers. You don't need the extra amp.Good luck
