It is a small investment when compared to current prices!
Now to be completely honest and transparent, my hearing is nowhere near what it used to be. And I am not without bias for a beautiful object built with care and craft. Additionally, I find that with an expensive kid in NYC, I no longer have the kind of disposable income that gave me my Nagra/Sonus faber/Teres/Schroeder/Allaerts system. I do miss that system (Nagra VPAs and Sonus faber Amati Homages are really a magical combination), but I think the AC cord from the wall to a Shunyatta Hydra cost more than the fully-restored TD 124 and at least 2 of its arms...added together. Far more appropriate given my shrinking frequency capabilities that I spend wisely. And MM, MI and electret carts from the 70s and 80s fit that bill. I really enjoyed my previous system, yet I really enjoy this current one too, just differently. I've said before that "What's Best" doesn't have to mean most expensive, or even best objectively. It means to me what gives me the most pleasure in my current context.
I just started rebuilding a pair of speakers I first got in the late '90s from Don Garber at Fi, called Pipedreams, designed by JC Morrison.I blew the drivers somehow, but Beaur (Fleetwood) was able to reach JC and get a nice bit of encouragement for me to replace the unobtanium Focal 7v513 mid-drivers (running full range to great success) with a few other options. These are in 1/4-wave tapered pipes, tuned to 50Hz. They are in 1/2" baltic ply, as per JC's schematic. In no way should they sound good...but they certainly did! And I will derive not just joy from their sonic resurrection, but pleasure from the act of restoring them. Would I take a pair of Reference 3A Reflectors right now? Yes! Immediately!! But for what I will spend on the Pipedreams in cash and sweat will be less than a tenth of the Reflectors, and I'll still be able to pay this semester's school tuition.
Just as an historical part of my story: the amp i use started life as a dumpster find in the East Village in 1997. I pulled a ratty Dynaco ST 70 out of a rat's nest of tenement trash, and brought it to Don Garber to see what he could do with it. This was back when he still had the shop Fi on 30 Watts Street in Soho (perfect address!) selling restored Altec, Marantz, and Harmon Hardon amps displayed on pedestals like art. He also represented JC and Noriasu Komuro, who happened to have a schematic for redoing an ST 70, using only the trannies and chassis. So for the massive investment of $375, Don built me Nori's amp, now known as the Komuro 70. It is, as far as I know, one of only two ever built, but the only one that looks like it does. And it sounds awesome. I'm so glad I kept it when I got the Sonus fabers and it just didn't have the juice to drive them.
Let me know what Joseph can do with your M-A. If he can restore the cantilever, perhaps I can send you mine as a loan so you can compare before you do anything else! My only other M-A is a 2002e that Joseph did the same thing to, so at this point these are both "JL/M-As."
