Mac MA 6100 worth the $$ to update? orig owner

Thanks for the advice, I have learned some things. I am using the SME type III tonearm and the Denon AU - 320 cartridge transformer(forgot to mention it). Per your suggestion, I checked the woofers while playing a vinyl record, the bass was prominent, woofers well behaved. Mattmiller, you stated a comliance (sic) of 25. My specs for the DL 301 II read Compliance: dynamic 13 x 10-3m/N. I feel I should know more than this but do not. I will take yours and Effischer's advice re the upgrade to a new amp. Exciting, actually.
Should I resolve the electronics and possibly cartdidge issue before deciding on the speakers. Note that I am to audition the B&W preference 6 speakers this week.
Your input is very much apperciated

Your Mac will sound significantly better with a full refurbishing; new caps and parts, not merely a cleaning and calibration. I have some 70's Mac, Yamaha and Luxman that was refurbed and I love using them. But I agree that in pure sonic terms it is not worth the cost. But if you love your Mac and want to enjoy it for another 20 years...

Your amp is rated at 70 watts into 8 ohms. A little on the lean side for me. How easy are the newer B&W to drive in your space compared to your present speakers? I have owned a couple of these amps and I think the newer Mac's are better sounding to my ears. If yours is in good shape and you have the manual and original shipping box, it is still worth some OK $. You would like the 6600 much better. Just my 2 cents.

Thank you, Jihley. I am now looking at the MA 6600. I am prepared to replace the amp and speakers and the cartridge (which was purchased last) though I probably don't have 10 hours on it. What is recommended, replace speakers or amp first? At my age, I can afford the $$ but I'm sure my hearing isn't what it was.
Thanks for your time.

Transducers make a bigger overall difference to your sound, so speakers and cartridges should get first consideration. However, you will find that new speakers reveal other system flaws. Be prepared to start hunting for a new cartridge, tonearm and/or table if you do speakers and the integrated together. Also, consider the MA6700 instead of the 6600 - it will get you a MC input and going to moving coil would be a huge step up in image and depth that any B&W will easily reveal.

Above all, have fun and buy only what you like.
