I am looking to upgrade to new Mac speakers, possilby the xls 340's or 360's.
Would use the Mc-252 amp, or I could upgrade the amp too during the trade-up program. Ideas or suggestions?
Victor, your comment on the LS340 is interesting. I have a pair of LS340 and I do enjoy the softness of the sound. But I found that the bass are also too weak. I decided to add a PS112 for the deep bass. I run it for the very low frequencies only and without adding too much gain as I want to keep the beautiful sound of the LS340. In fact I am trying to correct the "weakness" on the LS340 in the deep bass with the PS112.
I have to say that I now have a very good compromise: bass with punch where I like it, and clarity everywhere else.
So far I am happy with my choice.
Brice.
The LS340s are not the kind of speaker that will impress you in a short demo but you can listen to them for hours and hours and enjoy every minute.

I would recommend the LS over the XLS.I suppose that is a matter of interpretation. I have a set of LS340s along with (2) PS112 subs and enjoy the sound very much. My cherry red cabinets are beautiful and well built. However, they weigh over 100 lbs. vs. only 65 lbs. for the XLS340s. The LS360s weight 165 lbs. while the XLS360s weigh around 100 lbs. The new XLS line affords more placement options and for some may not be as obtrusive as the LS line. Both the XLS340 and XLS360 have a second-generation five-tweeter bessel array which provides more power handling and clarity and improved soundstage and imaging. I personally do not like the appearance of the extruded aluminum enclosure on the XLS line but it is more antiresonant that the wood cabinet on the LS line.
I don't plan to exchange my LS340s for the newer XLS340s but everything being equal, if I were starting over again I would certainly opt for the improved XLS speaker line including XLS subwoofer.

I hear ya & agree...
I'm sure some prefer the XLS to the LS & size can definately be a fator. They are big by themselves, but the boxes are like coffins! I have a Dodge Durango (full sized SUV) and could only fit one of these things in my truck at a time. Let's just say my wife was less than pleased when we rolled them into the living room on a hand cart, but she's come around to accepting them & this addiction (er.. hobby) that we enjoy.
I only have the setup guide for XLS320s. In that guide it says for "low power amps" (up to 250 watts) to put the jumper on the positive posts. For "high power amps" (over 250 watts) put the jumper on the negative posts.....single wiring to bi-wiring on the XLS340/360? Mcintosh says that the jumpers should be used for low power applications, but they don't say what is considered a low power situation. Is my 6900 considered "low power" at 200 watts per channel? Anyone with experience here?

I think this setup is only used for single wire speaker wires. If you are using bi-wire speaker wires, I would not use the jumper at all.

It will drive them with ease. :yes:I do not know how well a 252 can drive SF Cremonas,

I've listened to the floor standing Cremona's even with an integrated NAD rated at 150w. My own Cremona A's sing like no one's business with the 75w from the 275 and just as well from the 501s.
That's the best way to know for sure. :thmbsp:I will try to get out there this week or weekend and hear what others are talking about.
