tlong1958..No I bought a MC402 back when it was the latest offering..Pretty sure it was 4500 ,maybe 5500,I don't remember what it was but I paid retail plus about $150 to ship it UPS...the 452 I bought much later used and dirt cheap only to flip for profit, which I did.I would never have Mac in my system after the 402 disaster.So I battled the factory and the dealer at that time and the only thing I was promised was from the dealer that if I ever had a problem contact them.I did wait long enough and sold that amp..but my story is true.
Mcintosh 452 vs Pass Labs XA 30.5
Hello everyone, I'm at the Mcintosh house and so maybe part of the answers will be taken for granted, thanks to the desire to try new devices I'm evaluating a transition from my current Final Pass Xa 30.5 to a MC452. Even the pre should be replaced by switching from an Xp10 Pass to the Mcintosh C48.
I use the Totem Mani 2, Audio Physic Scorpio 2 and Tannoy Eaton speakers in a listening environment of around 20 sqm at low and medium volumes.
I would like some advice from those who have had the opportunity to try, comparing these brands and the good interface between the coupled MC 48 and 452 and my speakers.
Thank you.

“On these fairly easy to drive speakers, both will work fine...”I beg to differ, you quoted me. They are an easy load for an amp, just not efficient so you need watts. Not looking for an argument but whatever wording you want to choose your advice was not appropriate.But you are, then don't quote me and then try to "cover" your inability to distinguish "bad load for a speaker" with "inefficiency of a speaker". A speaker with bad load impedance for an amp, with one that's just "inefficient", which in this case the Mani2's are, just inefficient and NOT a difficult impedance "load" for an amp. mizioaThe 30watt Pass to me will sound the best to a given volume level, but the 450w Mac will go louder. This volume level has nothing to do with the "load" the speakers presents, but the "efficiency", to which will give the higher volume level. As far as me saying the Pass will sound better to a given volume, that's because it's a Pass, and the Mac? well is a Mac, (a solid state with output transformers?????) bizarre! Cheers George |
Efficiency and impedance loading are two different measurement parameters in a speaker, end of story, your the one with the BS, with the inability to distinguish between the two, to mate amps up with. For those that are interested: An inefficient speaker like these Totems with low (80db) and fairly easy impedance load, can still be driven by a mediocre amp with less than average current drive, so long as it has high enough wattage for that inefficiency, to be played loud. But if that same speaker also had a nasty impedance load as well, then it still needs an amp with the wattage to go loud, but would also need that amp to have good current drive as well to handle the nasty impedance load as well to stay linear in frequency response at those low impedance dips. If not it would sound like a tone control at those impedance dips. Cheers George |
