Thinking of Magnepan ... finally!

@arafiq

For example, do I really need to treat the side walls?

I would wager no. I just removed all 6 of my side wall absorption panels, which are Primacoustic Broadway 12" x 48" x 2" of high density glass wool. Easy to do as they are just pressed on protruding triangular hooks screwed into the drywall.

I think Cannonball’s sax (Kind of Blue- So What) was a little further outside the speaker, and the tiniest bit of high frequency information and spaciousness was introduced, and the upright bass was a little looser with them removed, but if I had to pass a blind test I don’t think I would. This is in an 11 foot width room- I would guess a larger room would have less effect. Room looks naked without them now so I replaced them. 

Due to dipole cancellation there is not alot of energy dispersed to the sides of maggies. Maybe the sidewall is a good place for the painting? If you wanted the sound of the alto sax to emanate from the painting that is.

Great thread @arafiq .  Having been on the fence as well with mags, this "thought" comes up, kind of like dipping toes into vinyl .  I have friends with 1.7i and have heard them many times and they do sound great.  They do things really well and other things that may or may not meet ones preferences.

I recently heard them again in a diff setting and although they do kinda wow you at first, it didn't take long to realize I don't think I would be happy long term - citing many of the same attributes you did, that's why this was such a good read.

The big soundstage etc.. is "cool" but to me always seemed a bit too much or "artificial" for lack of a better word.  It sorta mashes everything together compared to dynamic/point source.  That's what I miss almost immediately - the dynamics, pin point imaging and bass authority.  I run two sealed 15" subs so I should be OK if I decide to try, 

Maybe that's just an element I'm used to and living with mags overtime would fall in love, dunno.  Like you I have determined that its either 3.7i or the 20's and really its more of a "something to try" and not at all unhappy with current setup - far, far from it.  However, I'm not a constant gear swapper, I find something that gels/has synergy and stick with it for awhile.

I always read from experienced/established users/audiophiles that everyone should try planers, just to see - that's always my motivation.

One other note, you have a nice room and your comment about diffusion - I would recommend against mixing up different types.  For the front wall do all QRD's (one dimensional only) along with proper corner bass trapping.  I've tried it and it can mess things up (diffusion is tricky/complex and in all honesty professional adivice is highly recommended) - I have on front wall two dimensional skylines (vicoustic  DC2) which are hemispheric broadband diffusion.(about 12-14 panels).  Works well, but I "think" if I were to do it over, would put all QRD - at least from my research, so the usual YMMV, my $.02

An interesting observation for me today with my Mini. I switched over to my Schitt Aegir monoblock amps which run at 70 watts 8 Ohm in Class A. Not sure about 4 Ohm. All other gear was the same.

The sound was a little more rounded than my Sander Magtech (Class AB). The sound was also rather boomy. I was getting fatigued and was thinking that I needed to put some of the GIK panels back behind the speaker to tame this sound. However, I gave all my panels away so that is not an option anymore.

I put back my Sanders Magtech and the boominess and fatigue went away. This was without any acoustic treatment in a weird room..

I am assuming that the Mini was not well served on the low end by the Aegir and the boominess was the result. My takeaway is to use a very powerful amp with the Mini. I am surprised I am not getting any sonic issues with the Sanders. It sounds great.

After a few more days with the 10 AWG Blue Jean speaker cable, it is no longer a question of whether I am keeping the cable. I put my Audience FrontRow up for sale. I am not even trying it on the Mini because I would need to rearrange some things to make the short FrontRow cable work. I also do not care for any marginal improvement, if it even exists, with the FrontRow. The Blue Jean cost under $300 for 2 sets and the short FrontRow speaker cable was about $5k MSRP.

Now that the LRS+ version has replaced the previous version, which was already said to have incorporated all new lessons learned by Magnepan in the original LRS version, and received much acclaim, do any of the owners of above entry level now older Maggies feel like the system has failed them? What if, after buying the best speaker and before system, you find out that you're already supposed to be dead, unless it's at a minimum of 10,000 watts, when you just heard Attack by The Exploited, oh, and with a sub?

How was the military intervention, since Reagan? Was there ever anything even YOU could find out, while James Bond was you first?

A potential customer's only hope of survival may be in a review of that track on any Maggies, with a comparison to what we should expect dynamic drivers to roughly be. What if someone broke into your home one weekend day, and demanded to hear your best rendition of that track, to find out whether you live or die?

@audioisnobiggie I don't think I understand your post. What is the point you're trying to make?
