Boron vs aluminum for cantilever on DL301 Mk2 retip?

I’ve never heard one.

I think it starts as an overpriced Elliptical on Aluminum, the only thing I like is it’s nominal 1.4g tracking force.

0.4mv and 33 ohm coil is an ok combo, a 12x SUT would result in an impedance shown of 326 ohms, a 10x SUT would show 470 ohms (guidance formula 33 ohms x 10 = 330 ohms)

Specs say separation 28db; channel balance 1.0db, not bad, if you liked it’s sound, perhaps rebuild it with an advanced stylus shape on boron

Any rebuild, I advocate an advanced stylus shape, Shibata, MicroLine, a variety of other names/patents; SAS; Special Line Contact .......

 and I like light/stiffer cantilevers, boron rod is the premium offering from many new cartridges today, tubes are not available except buying NOS or used. I’ve had VAS rebuild several of mine and my friends with Contact Line on Boron Rod

Here’s a chance at my favorite MM, an AT160ML with MicroLine on Gold Plated Beryllium, I don’t know the seller, tracks at 1.25g

Tomorrow I get to play my NOS Shure V15VxMR that arrived this evening, with Microwall Beryllium Tube. It produced the tightest bass I ever heard before I broke the cantilever in a clumsy moment. 

" It offers the highest known trackability at 1 gram of tracking force, enabling extended record and tip life while minimizing distortion and record wear. The cartridge’s ultra-low effective mass beryllium cantilever provides a stiffness-to-mass ratio of 6.25, the highest of any cantilever ever made, resulting in unprecedented high-frequency trackability"

This 3 LP box set has a great collection of music, with lots of BASS, not demo tracks, all/each very listenable on it’s own accord, I highly recommend it.

I have had cartridges serviced by VAS and Soundsmith and, in both cases, they recommended leaving the boron cantilever and retipping only. This may have been due to the boron cantilever, but my point is to go with the retipper’s recommendation. They know what works and the last thing they need is for you to tell them you don’t like it. I’m not saying the original material is necessarily best. You may well prefer the cart with a different cantilever, but I would still give the retipper’s opinion a high degree of deference.
