I'm awaiting arrival of MC451. I'll let you know my first impression. I'm pairing them with the MC12000 and B&W 801D4s. My source will be an Aurender A15.
Mcintosh mc451 mono - anybody use this new dual amplifier?
I like idea about biamping speakers with tubes going to mid/ tweeters and solid-state going to bass drivers. It requires you to adjust the gain and crossovers to each speaker which doesn't seem so bad.
Basically it's a Macintosh 600 watt mono and a 2301 300 W tube amp combined under one roof and brought together by an internal crossover/gain device.
Has anyone had any experience with this new amp?
@emergingsoul , I enjoyed the MC451s. I had them paired with 801D4s. Very musical. Great for those who love acoustics. Synergy is very important. Some say the 451s do a better job at providing a more natural sound than the 901s. I haven't heard the the 901s.

I don’t post here often, but I have a set up very like you describe. The VSA vr4 jr’s have built in crossovers at 200hz and are easy to bi-amp. I use a Mac 462 for tv and movies but use it as bass amp for music. I currently have 3 tube amps that I’m comparing now, an ARC D 70 II, a MAC 275 vi amp, and a MAC 1500 receiver with the preamp bypassed to use the amp section only. The 275 has more air around the instruments, but less dynamic jump, though not sluggish or heavy. The D 70 has more dynamic jump, but needs 6550’s to really sound best. The 1500 was a real surprise, almost matching the ARC in dynamics. Tube sets are very important and needed a selection process to get each to sound its best. 275, winged C 6550’s, nos Sylvania at7s, and os Teles ax7’s. The stock tubes were grey and sluggish, but the amp came alive with the upgraded tubes. An expensive upgrade. The D 70 is best with 6550’s and os 6dj’s etc. The 1500 needed TS 7591’s, and os Teles au7’s and a Tele ax7. Hope this helps. Each is acceptable with the right components, with the 275 in most need of careful system matching. The above assessment was made without the 462 running the bass, to give a better picture of each amp alone. |
