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

Also, I would check on that DL-103 with the tonearm you are using. This cartridge works with heavy arms like the ones used by old DJ record stations. And I am not sure if it is a good fit for the table/tonearm you are using. The DL103 has a comliance of 25. I strongly suggest you try a different cartridge like a Ortofon red or blue or a Shure. Something with around 10 compliance would be a world of difference for a medium sized tonearm. Do you notice your speaker woofers pumping in and out way too much when you spin vinyl?? This is a great indication of a mismatch with cart/tonearm.

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.
