Mac 275 questions........

After some months of up's and down's with my ASL Hurricanes (just seemed to never stay operational for longer then 2-3 months) I have decided o retire them and get the McIntosh MC 275 (2 amps).

I have some questions for you all and appreciate any input you may have (especially form Mac owners) but opened to all.
My speakers are Infinity RS 1-B's and I will be using the amps to drive the top end of the system (EMIM's and EMIT's). I have a Perreaux 3150B for the bass columns. The Infinities are rated at 4 ohms.
I plan to listen to one amp on top ( I will get one amp in a week) and then when I get the 2nd amp ( a week later) run both in mono.
What will I hear with each application? First with one and then with both? Also can any of you let me know if any of you compared the Mac 275 (in mono) 150 watts with the Hurricanes 200 wpc? The Hurricanes were great but I just could not live with them being up and down so many times.

Thanks to all for your input.

Hi Neil, Thanks for the response. Which tubes are you referring to...the KT88's? What do you recommed? I have someone who works in NY for a tube dealship so I might be able to get some new tubes at a savings. Your comments are valuable!

My (moderate priced) tube recommendation would be a quad of the new reissue Gold Lion KT88 (about $200) and some NOS Telefunkens for the 12AX7's and 12AT7's. If you'll send me your email address, I'll give you more details when I have some time.

Neil, thanks for the heads-up with regard to tubes on the 275. However, this is the first time that I have heard of failures (tubes blow up) from McIntosh? I totally agree that better tubes will probably improve (change?) the sound but I hope I am not going from the frying pan into the fire? That's the reason I am loosing the Hurricanes.....amp failures.

I just got 2- 275's. Im waiting for the C-2300 to come in to hook them up. Where are the stock tubes made? I am curious about the tube failure? That is a bit disapointing. I am also interested in the new tube replacment.

Yes Chiroman, we will have to compare our finding when we get both amps up and running. My 1st map will be in this Saturday (Jan 5th). The second should be in a week or so latter. This will give me some time to evaluate the 1 versus 2 amps etc.
What are your amps driving?
