![]() Early 45 as Lps were mono and in the late '50s stereo started to appear. 45s are micro-groove records pressed into vinyl or molded polystyrene which is actually more prone to wear than vinyl. You have moved into 45s which are more similar to Lps than to standard groove 78s. Have lots of fun with this “antique” sound of days gone by ! :wink: (STANTON used to sell an MM Cartridge with a set of interchangeable styli ( unfortunately it’s NOT a true MONO cartridge…)įor “higher requirements” there are the Audio Technica AT-MONO3/SP and the Ortofon “S”PU Mono Shellac 65 CG (sadly at a very steep price – but with an excellent sound !) I can only support the notion that 78 shellacs sound better with a “true” mono generator and if you have badly worn and/or old records with a suitable stylus. ![]() The complete mass of arm + system & counter weight is essential – and you could have a heavy cartridge and low tracking force….īut as mentioned above: I would not really worry about the arm mass, AS LONG as it fits the cartridge you select. The “weight” of the tracking force should have little impact onto the total force onto the arm bearing. Will the bearings of "ordinary" tonearms be able to withstand these forces without damage, over a sustained time period? So not a "religious fury" (mind you that "modern" politicians are not known for that, but they did inflict much more human and philosophical toll) but a humble opinion based on experiences and theory for the fit.īalder wrote:What I am concerned about is the heavy tracing forces required for 78s. Yet indeed nothing should be more telling than a real "live" trial between a higher compliant MONO cartridge and a lower compliant one powered with a "neutral and clear" (show it all) sonically phono set-up. But with two speakers, one could be inclined to hear differences in the channels. I can understand that a STEREO cartridge summed into a MONO one should sound even if plugged with only one speaker. As I have know to discover with my vintage 45s. This is where I'd have believe that a MONO low compliant cartridge on a heavy mass tonearm will not only make those 78 listenable but truly enjoyable sonically. Not just the cartridge compliance, the stylus cut, the MONO lateral read or the single bodied cart, but it's the whole that makes it. Only after the evolutive DIY tweaks I did enhancing progressively the effective mass of the tonearm, the cartridge started to do much more than OK. This DL-102 was fit on a SME3009 'Improved' S II and it did OK. I come from a long way and I know how my vintage 45's have benefitted from my low compliant MONO cartridge with a large conical stylus. ![]() Hi Phil, no offense intended, but myth are for believers, not knowers. I can properly sum my stereo cartridges to mono for either lateral or vertical and I'll say that while 78s (and mono lps for that manner) are best played in mono, a properly summed stereo cartridge just a good as a mono cartridge. As I said above I have both mono and stereo cartridges. On the mono/stereo cartridge thing: I realize that this is argued with religious furor. They will not even play vertical records. Some mono cartridges such as my RPX should never be used with stereo records or vertical cut records. It is an elliptic stylus for standard groove 78s and they have sound samples comparing it to conicals on their site and I'm very tempted. My next 78 stylus (for the Shure) is likely to be the N44-3e from Esoteric Sound. The RPX is a mono cartridge from the '40s with lower compliance, but the extra counterweight makes the SME into a more massive arm. Of coarse it can't be used with vertical cut records. It also works well on standard groove 78s. It is somewhat massive and requires an additional counterweight on the SME. It also works well on the 78s as well as the 80 RPM vertical records. I also have a stylus assembly which has been re-tipped with a 3 mill stylus for the Sonus. ![]() For micro-groove vinyl 78s I use the same Sonus Blue which I use for Lps. I can also play vertical cut records such as Edisons and Pathes with it. It tracks at 2.3 grams and works very well on Shellac 78s from early acoustic from ~1914 to standard groove 78 vinyl 78s from the '40s. I play a lot of 78s and my main setup is an SME3009 with a Shure M44 body and an Astatic packaged Shure stylus which is supposed to be a replacement for the Shure N44-3. I think the notion that you need a massive arm with a low compliance cartridge is a myth. The arm which you need is determined by the cartridge which you are using as with Lps. ![]()
