Anthem mrx700

rklpoon

Spotted captioned new AV receiver today in local av magazine. List price $26000. phoned Excel and found out it is $16000 with ARC. But only 2x120W and 5x90W.  Already made an appointment on sunday to listen. Will consider this one and the Yamaha 3067.  Will dig out more details of the M700. Anyone with Anthem experience care to comment?

yes, that is why so cheap. The MRX900 may be made in Canada but costs $32,000.

ARC(Anthem Room Correction) - copied from relevant AVS forum thread:-

How does the MRX 300/500/700 ARC implementation compare to D2v/AVM50v?

A: ARC consists of software that runs on a user-supplied computer which calculates a room correction solution and a DSP chip in the receiver which implements it. The ARC software is the same for all Anthem A/V receivers and processors. The MRX DSP is about half as powerful as that in the D2v/AVM50v.

Nick @ Anthem elaborates:
MRX 300/500/700 DSP has around the same amount of number crunching ability as anything in the price range, which is around half as much as AVM/D prepros using ARC (and PBK for that matter), which have as much as pro systems in the five figures. This means that MRX 300/500/700 corrected response usually does not meet target response as closely as AVM/D, thought it's also usually not too far off.
The other difference is that correction range not only defaults to 5 kHz but cannot be made to go higher. Correction above 5 kHz is not normally recommended regardless.
Another difference not dependent on ARC is that MRX DSP uses crossover frequencies of 60, 80, 100, 120, and 150 whereas AVM/D allows 25-160 in 5 Hz steps. It relates because ARC selects the crossover frequencies based on in-room measured response.
The practical difference depends on the amount of correction the room speaker/combo needs, and this varies greatly. MRX-ARC still improves things regardless, using the same principles as the other ARC.

Any high-hand Ching cares to comment the effectiveness of above stripped down verson ARC pls?

Went to Excel with randyma today. Using Paradigm speakers and found at first the sound is not that powerful(in a 400 sq ft environment). Later found out due to the Dolby volume was on. Turning it off made it much better and should be enough power in home use(90Wx7). The price also included a one time on-site installation.

Now would choose between Yamaha 3067 or this one Anthem MRX700(700 is $500 more expensive).
Yamaha has more features:-
2 HDMI out - 700 has only 4 in 1 out (but the Cary 11A only has 2 in 1 out, no video processing chips, cost $24000+ brand new and also made in China-correct me if I am wrong). 700's (only 7.1 channels) selling point is Canadian brand MIJ and stripped down verson of ARC (D2V processor costs over $50,000-not for sure because way out of budget).

Any additional comments randyma pls.

You are fully report on it. It may be Excel is only set up with 5.1. The surround is not fully to cover as my listening on 3067 in Yamaha show room. It is power enough and the detail is also good in 400 sq ft show room with 5.1 only. If not further to upgrade into 9.1. or 11.1. It is a good choice on it. It have Europe style on it.

randy hing, pls elaborate what do you mean by Europe style and Japan style. I think I'll wait for some local av magazine's review. The MXR500 is $4k cheaper snd only some 15/20W less and without HD radio(don't know the HD radi works in HK or not) ands since I still a Emotiva UPA-2 125Wx2 the 500 looks better c/p to me.

randyma

Europe-have exactly power. Japan-not exactly full power as specification. But 75wX5 is not power enough.

My upa-2 2x125W driving the L+R should help.

However above the 4 surround channel-75W vs 125(L&R). It is too big diffrent. No good.
