Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

Wyred 4 Sound Mini MC 7 Channel (MMC-7) Amplifier Review: Discussion Thread

For the Full Review: Click Here!



Summary: If I could provide you with an analogy to compare this amplifier to your typical A/V Receiver, this is like the difference between driving a Toyota Camry and a Lexus IS350 - the MMC-7 is more refined, more powerful, and better built. The MMC is just plain better at being an amplifier. Your friends will envy this fine piece of engineering you have acquired, all the while scheming to outdo you without breaking the bank. In the case of the MMC-7 your friends are in for a challenge, outdoing this 7-channel amplifier at any price point below three thousand dollars might be doable, but competitors have a lot of work to do before they can give EJ Sarmento and the fine people at Wyred 4 Sound anything to worry about.

Highly Recommended

Due to weight constraints I have been doing a ton of research on Sunfire Amps....this review is intriguing to say the least. Excellent write up. Good looking amp to boot.

Re: Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

I definitely think this amp is a contender for you if you're considering Sunfire. In any case, I can safely report that I chose to keep this amp for my system after the review ended.

Re: Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

Sorry if this sounds like negative feedback but a few statements you made... I would like some clarification on them

Quote:
where my Onkyo was warm and laid back the MMC-7 was startlingly neutral with excellent resolution and clarity.
With which speakers did you perceive your onkyo as warm and laid back... was this specific difference repeatable with different speakers? How would you say this perception was a function of the S6's electrical load?

Was listening done in source direct mode?

Were the levels matched to within .1db?

Quote:
Where the SC-37 was tonally neutral and transparent, it did sound somehow more digital than the MMC-7 does.
What exactly do you mean by "sounded more digital"? Do mind clarifying this?

It's implied by the tone of your post that you believe everything needs to be qualified by electrical explanations/objective data. While I agree with that spirit allow me to clarify that this is not an objective evaluation, this is my personal subjective opinion and nothing more, you can choose to take it or leave it. That said, i'll do my best to answer your questions below.

All listening tests were done using the Paradigm Signature review system, the sonic signature of my Onkyo receiver was consistent across three different speaker systems including the Paradigms, AV123 Rockets and Onix Reference 1's.

The S6 specifications are available here: http://www.paradigm.com/products/par...s/signature-s6

As I stated above, since this was consistent across speaker models the electrical load of the speaker here is not my main consideration. This is a subjective account of my impressions of the sound of this amplifier - I cannot quantify what is ultimately a subjective determination. That said, I generally find class A amps to sound warm while Class D sound neutral - the electrical explanation for this phenomenon is unknown to me beyond the most basic fundamentals. If you are looking for an electrical engineers analysis, this isn't it.

All listening was done in source direct mode at all times across all speakers/amps. Levels were always matched and checked prior to a critical listening session.

As to sounding digital, I'm not sure what the cause of this was honestly - it may be high frequency distortion or feedback, but the only way I can describe it is to compare listening to a middling bitrate MP3 such as a 128k MP3 vs a FLAC file - you can hear some form of distortion or compression that sounds "digital".

Without arguing psychoacoustics and bias to the end of time, suffice to say that I heard a very noticeable difference between the two amps, with the SC-37 definitely not sound as good to me.

Res non sententia.

Re: Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

That's fine. If there's differences I'm sure a person could measure and quantify but with subjective tests I just like to know that the controls are in place. Thanks and like I said, I didn't intend for it to sound like negative feedback. I firmly believe that two great amps should sound identical but I'm also not a person who believes all amps are great and I've never owned an Onkyo before.

I've heard from a very reputable person in that past that pioneer receivers can have a grainyness to them inherent in poorly designed Class A/B amps (although ICEpower is class D). I just didn't know if "digital" meant the same grainyness or somethign else.

Re: Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

I'm really not a believer in "audiophile" descriptions of sound myself - but it's really hard to nail down what I heard with the SC-37. At the time I was very impressed by it - but comparing that Class D ICEpower amp to the MMC7, there is a large difference with the same technology being used.

I really don't know what factor to blame that on - it could even be a result of the SC-37's processing, but I can say with certainty that the MMC is a much nicer sounding class D amp.

Re: Wyred 4 Sound Mini MC 7 Channel Amplifier Review Discussion

I'm thinking of going Class D myself, at least for the front 3 speakers. Mine will be Hypex, not ICEPower, though. I've read some literature on ICEpower in the past that has me somewhat "insecure" about it. Perhaps that correlates to your experiences between the wired4sound and the pioneer. It may be the implementation, not the technology, that causes my insecurity towards ICEPower. Unfortunately the wired 4 sounds just don't do it for me aesthetically.
