McIntosh :MC302 Upgrade from MC162 is it worth it?

It sounds like you already have the MC302 on the way. I can tell you that you will hear a totally improved sound from your system stepping up from the MC162. I had a MC7205 which was a 5 channel version of the MC162 and changed to a MC352 then later a MC402. Big difference, more depth, deeper bass, faster transients, much quieter background, warmer mids with more delicate highs and no brashness. If you love your MC162 as it is a good amp, you will absolutely love the MC302. A totally different topography to the structure of the circuitry. Mcintosh has come a long way since the MC162 was produced on their amps. BUt they have made two levels of amps for years even back when the 162 was new. They made/make a non-autoformer like the 162 and new 205/207 and those with autoformers. You will be getting the Autoformer with the 302. This adds a different sound as well as a double balanced output stage that quiets the noise floor considerabley. I suggest that you give Chuck Hinton a call at Mcintosh and he will give you a much better explaination of the differences. Their 800 number is on their website, great people at Mcintosh. Even if you are buying it used they still treat you like you bought it new.

Let me know what you think once you get the 302 broke in.
I am so sure that you will think you have a totally new system.
I was wrong however the 302 doesn't have the double balanced out put they don't employ that until the 452. But the biggest difference will be the autoformers and that presents the biggest changes. The double balanced only reduces the noise floor which will be considerably less than the 162. Plus you get LED fiber optic ligting instead of incandessant bulbs. I was forever replacing mine on the 352 and 7205, and that got old real quick. Enjoy!
