MC 402 vs. MC 7300

Winger, at the CES last year they had the Dali MS5 or 4 with the MC402 and MCD201 direct sans preamp and it sounded fantastic. I dont usually care for CD direct but this combination had excellent synergy. I could only imagine how much better it would sound with either the MCD301 or the new MCD500 SACD player as they both have variable outputs. FWIW Gallo also was running the MC402 with the MCD201 without the preamp on his reference 5LS line array speakers with equal results. Skip the preamp and upgrade your source to the MCD500, you will not be thinking about the 501's. 402 is more than enough to drive the 803. Ask your dealer if he will loan you a player or bring one over for an in house demo. Good luck!

the mac mc 402 is anice amp i have the older mc352 running martin logan sumits i play my music loud the amp never runs out of power i use a mvp861 for a d player sounds very rich

Back to your original question - I am unaware of an amplifier currently made by Mcintosh with a model number of 7300. There is the 6300 and the 7000. As to driving the MS5 with these different models, The 6300 would be a light, the 7000 will likely work fine for all but the loudest listening levels, but at those levels, my guess is that you will get the power guard to flicker. The 402 would be my choice.

The MC7300 is a 1992 amp. 300W per channel. It's considered somewhat of a classic McIntosh amp by some.

Another option to consider with the "best bang for the buck" would be to buy NOS MC352/C41 amp/pre combo from Audio Classics for less than what a new MC402 would cost.

LED kits are also available for both-no bulb changes!
