Surprisingly similar (or maybe not) to the target curves marked in green on pps 4, 7 & 8 in the RoomPerfect whitepaper (see attachment).

If you're finding my "music" curve works well for movies, then the music curve should have another 6 dB boost in the bass! eek.gif

So what would your movie curve look like? Would love to compare.

Roger, you've confused the non-engineer.... I thought what you posted was a movie curve, something along the lines of the jbl curve, maybe salted to taste....

What he posted IS the JBL curve. He just prefers to use it for music. If I understand Roger correctly.

I also have the option of a similar highpass near 20 Hz, or running without the highpass. The latter is my normal mode. I only activate the highpass if movies are too bass-rambunctious. wink.gif

I just took a listen with The Dark Knight, and while most of the curve is great, bass is too hot...need to see if I ca figure out how to reduce that hump

Actually..I did test a couple of other movie clips. Overall I think it could use a ~3db cut in bass. I still enjoyed Dark Knight smile.gif

How is the MX150 for 2 channel playback? Would you recommend a pre amp w/pass through or is the MX150 sufficient alone???

The overall quality and features of the 151 makes it a superb high-end two channel preamp, though you will have divergent views on digital vs analog among other topics.

The 151 converts all signals to digital, including analog inputs. The benefit of this is the ability to use Room Perfect, which I find as important for two channel as I do for multi. This also permits use of the 151 crossovers and subs. Some argue they desire a pure analog path, which you will not get with the 151. And unless you have enormously capable full range mains, the use of well-integrated subs is important, especially if you listen to more contemporary mixes that go deep (I listen to Brian Eno, for example, and his mixes on a number of his more recent releases exercise my subs frequently).

Some prefer a tube-like sound; if so, then using the HT bypass modes of a mac tube amp, or anyone else's for that matter, is an option of course. But you're losing your subs and room perfect. (Well, you can add the 2 channel MEN-220 from McIntosh after the tube preamp to regain Room Perfect, but you're adding about $4,500 to your system course, introducing a/d/a conversion - you might as well stay in the 151 domain from the start).

I use a McIntosh D100 DAC to feed the 151 aiff files from a Mac mini, and enjoy it immensely.

The more I read about the MX-151 the more I find it interesting, I wish I could hear that room perfect demo, it might make me sell the SSP-800!

 

Not sure I could justify paying twice as much!

Well, you're getting quite a bit more - an integrated high end multichannel room correction solution ( with the mic and stand!)

Hardly twice

$9500 retail for the Classe vs $12,500 for the mx151

So you should proportionally not pay anywhere near the 151 MSRP either...

Hey guys, U gave been reading a bunch on the 151 for my new HT. I am doing a large diy build of AE/BMS/SEOS components, and plan to run with high quality pro amps for active eq. I have also had the opportunity to audition the 151 locally, but not done any comparison back to back, or on anything like I'm building. Anyone have experience in this arena?? Thanks in advance guys

Hahaha, you know, after reading my initial post I'm not sure I can see the question in it either biggrin.gif

I guess the question is do you see any reason that going with the 151 over something like the dhc80.3 or Marantz 8801, in a setup like mine is not worth the upgrade cost?? I feel like we are designing and building great speakers and that the amps are very capable, but I know most guys with this unit seem to have high end commercial speakers, amps, etc. I have to assume that if this processor is able to improve sound field, etc with a high end commercial speaker then it should offer all the same advantages to my setup...would you agree??

What I can tell you about the McIntosh with Room Perfect is it does an excellent job correcting room issues while retaining the character of the speakers. Both Thrang and I had the Marantz 8801 and while excellent for it's price, the MX151 brought my system to new heights. Beyond any processor I've owned previously. I think Thrang will agree as he's experienced similar results.

What did you think of the MX 151 when you auditioned it? Key question, was Room Perfect engaged and was it configured properly?

The 151 is fantastic, but can only reveal its true colors in a system that is otherwise equal. When you say pro amps and building speakers, its hard to know what the audio characteristics of this means (I tried a few pro amps and got them out quickly, as I did with pro eq gear). I can tell you that with my amplification, speakers, and room, the 151 has made a substantial improvement, one that still thrills every time I play movies or music though it, and unlike any other processor I've owned, which includes: Denon AVP-A1, Classe SSP-800, Marantz 8801, and the Integra 80.3, along with short stints trying Denon A-100 and Pioneer SC-57 as pre-amps.

It's also a budget question. If 12k is gong to squeeze other important aspects of the build, perhaps look at something else. If its proportionally reasonable, go for it, assuming the rest of the chan is not weak.

Sorry, I guess more detail needed on that.. I am building very high quailty speakers using the BMS CD coax 4594 paired with a seos 24" waveguide and dual 15" AE TD15M woofers. They are being designed to perform on the levels of Seaton Cats, JBL Everest, etc in terms of high fidelity and super high eff.

The 12k can be spent on it, just wanted to be sure that other elements aren't holding back the 151's capabilities. My reasoning behind the pro amps is that it would take approx. $50k in Mac amps to run the combo acitve/passive configuration I have planned now. If for some reason I find that going full passive gets me there, it would be a whole different story. 9 channels would be much easier to afford on that front than 18 or 21. This system will be movies and sports only, as I have a Revel setup for music listening in another room.
