Just went after a Mac 452 on a friends recommendation.

donpepe An amp cable of running into a 4ohm load continuously without breaking a sweat, would be ideal, as this graph shows most of the bass will present to the amp as 4ohms, and that’s where all the power is needed. https://www.stereophile.com/images/816PSBT3fig1.jpg The minimum value is 3.5 ohms at 85Hz, and the phase angle (dotted trace) is generally low. Any amplifier that is comfortable driving 4 ohms will have no difficulty with the Imagine T3. Whatever you get, see if Stereophile has done a review on it, and see in the test bench measurements if it’s happy doing 4ohms. Cheers George |
So, would you still be looking to upgrade the amps or are you now happy with the way your system sounds (TT noise notwithstanding) with the 21A? What phono pre are you using with the Belles? In reading the Soundstage review of the 21A there was no mention of noise with vinyl (he was using a Belles phono pre BTW). |
I am happy with the 21A but can't ignore the noise. I have (sick man) be looking today for tube preamps on this site, i know i can't any that interest me. The reason being that I ordered a McIntosh MC 450. George:Mcintosh literature reports 450 watts across 8,4 and 2omhs.Sadly, i have never heard the 452 bought it at the urging of a friend who loves Mac's. I heard McIntosh amps when I was a young audiophile (about a hundred years ago) and kinda remember liking the full, round sound.P.S. I had a large wood stand made for me, when all was set up,every thing sounded better than before through both pre amps. If i had waited till after the rack came I might not have bought the 452, alas.
