Audio research vs McIntosh
any comments on those who have auditioned both brands. specifically the 6SE preamp and the reference 3 phonostage compared to the mcintosh c1100 and c12000 preamps using for now mc462 amp. thanks.

never been a Macintosh fan, i prefer the arc gear by a mile. much smoother and accurate sounding imo

I think ARC and Mac are both great brands and I own some of each, but their sound is different. I think ARC gear typically sounds more alive, more dynamic, more up close.

How many hundreds of hours does it take for your ARC amp to burn in before this is true? As I understand it, it takes hundreds of hours before an ARC amp is "burned in". Next you must wait 20-30 minutes after turn on for the amp to stabilize sonically, and so on. And then there's that noisy fan. With my 3500, it is ready by the time I sit down after turning all gear on, i.e., about 20 seconds. It requires no fan. It is more powerful than most high powered solid state amps and far more powerful than a 160M. As far as the sound, it is beyond reproach. I would prefer it to Robert Harley's M10, see p.146 TAS September issue. My bottom line opinion, it is by far the best amp I have heard. It handles my XVX like it is a baby. The XVX has a minimum impedance of 4-ohms. Let's be real/genuine. Although everyone has a right to an opinion, an off the cuff comment like yours says more about your knowledge of high end audio than it addresses Ed's question. Best Charles |

I own both. ARC is clean. Mcintosh is lush. Even their solid state stuff sounds like tube gear.

I switched from an all McIntosh C1000 pre and Mac 2102 system (which, at the time was my home system) to Arc Ref 5 pre and ARC Ref 150 after I heard them side by side at a dealer. McIntosh presents a sound that is rounder, but less transparent, especially in the midrange. I heard things in the midrange on the ARC system that I had never heard at home. For example, I could tell there were 2 back up singers on one track in a Van Morrison cd that I was never able to discern in my Mac system or the one in the store. On a different cd, I heard minor (in terms of amplitude) instrumentation on the ARC system in the midrange that I never heard before through my Mac system. I was bothered by the fact that my Mac had, unbeknownst to me for years, obscured important musical details.
ARC does have more of a 5th row sound vs a 20th row sound from MAC but also a more colorful (and I don't mean editorial color) sound. The switch from Mac to ARC was some time ago, but I have never looked back and now have moved up the ARC line over time--enjoying each step up. I am now as happy with the ARC brand as I used to be with the Mac brand.

As far as resolution goes, I have heard this before, mainly from folks that have switched from Mac to AR. In the recent TAS, Robert Harley states on p.30 that the ability of the Magico M9 to resolve very fine detail is phenomenal. He states that for the first time he heard soft underneath the music vocalizations on the first track, "I love Being Here with You" from Dianna Krall's Live in Paris. Robert has as his reference an XVX with two Wilson Audio Subsonics for subs and the best solid state amplification. It is state of the art. I was surprised to hear him say this, because my "meager" system compared to his easily resolves the multiple extremely low level vocalizations on this track and I informed him of such. I suspect that you are running your Alexia's off the 8-ohm tap creating a severe speaker/amp impedance mismatch between your amp and speaker. When you are not playing music very loud, say between 3-35 watts, the Alexia-2/ARC 160M will obviously provide good sonic results. However, I humbly believe that my Mac D1100/MC3500 MK II will provide significantly superior resolution at any sound level, much tighter more resolved bass at any level, a superior more resolved midrange and treble at any sound level, and very importantly, the ability to turn it up when desired. I run my XVX off the 4-ohm tap because it has a nominal impedance of 4-ohms. I can tell you that you are creating significant amounts of audible distortion if you are running off the 8-ohm tap. You are also stressing your amp. I believe mixing Mac and AR gear a mistake. Their design philosophies are quite different. I have many classical and popular recordings that at high sound pressure levels require significantly more than 140 watts or 320 watts for that matter. The XVX needs 500 plus clean watts at 4-ohms to achieve the dynamics I require. I do most of my listening at 3.5-35 watts but there are plenty of times when I feel the mood, that I want to turn it up. On peaks the 3500 will easily do 700 watts. I have movies and live DVD performances that require a lot of watts, many more than 140 or 320 for that matter. A 3500 does not run hot and does not require a noisy fan. No matter what the sound level, I can place my hand on the tube cage without pain. It can drive my XVX to insane sound levels easily as you can see below, pic taken playing the Tangerine Dream CD, Phaedra. You never want to clip an amp, the dogma that tubes "safely" soft clip notwithstanding. It can destroy the tubes and damage the amp. The 3500 has an advanced clipping protection circuit that really works. When I see an Alexx or Alexia driven by a 160 mono, I know the music to be dynamically limited (compressed) and at a relatively low sound level (1-50 watts). Nothing wrong with this if this is your cup of tea, but not for me.
