idler wheel vs direct drive technics impressions


I just purchased on Audiogon from a great 'goner in San Jose, Kurt, the lenco l-75 idler driven turntable which had been heavily modified by Jean Natais with a beautiful cherry plinth. The tt is set with a rega rb-700 tonerarm and a shelter 501mk2 low output mc cartridge.

I can only give a very preliminary comparison of the lenco l-75 versus my other turntable the technics sl-12105mg.

I thoroughly enjoyed the technics directdrive turntable driven by a well regarded benz micro ace low output cartridge. I think in many ways its the perfect low budget table. It provides accurate speed, ample bass, easy to use, inexpensive, and provides for numerous upgrades. I upgraded mine with a tonearm dampen kit and a better turntable mat.

The lenco l-75 is using a new shelter 501 mk2 cartridge which is a highly regarded under $1,000 cartridge. Since the cartridge is still breaking in my observations are merely preliminary. The tonerarm and cartridge have only been set tentatively until the cartridge is fully broken in. At that point I will have it professionally set with proper vta and stuff like that since I am not an expert in these matters and want it done optimally.

Even at the outset one can readily tell that the Lenco is a superb sounding tt with a wonderful sense of rhythm, ease of use, with wonderful imaging and soundstaging.

Many people seem to think that you must go with belt drive or direct drive but the idler seems to me to be the perfect combination of the two. It does not have the speed issues that belts sometimes do (nor need belt replacements) but has better separation of the platter from the plinth than most budget direct drive units. The original lenco l-75 did not have the heavy plinth necessary to optimize the sound but the custom modified ones that you can buy from people like jean natais or make yourself avoids the pitfalls of the original units. The Lenco like the Garrard tt's are a less expensive logical evolution from the technics without spending a lot of bucks. Its nice to know you don't need to spend $10,000 on a tt and tonerarm to get even more analog glory than the tecnics. I would reiterate that I think the Technics is a no brainer purchase in the $1,500 and below category. I think the Technics was better than my previous $6,000 Marantz reference sa-7s1 cd player (albeit not nearly as good as my current playback designs cd player which is better than even the exalted emm labs equipment I used to own)

Have it professionally set up BUT only if you are sure that the person knows exactly what they are doing. I use to be an audio dealer and set up a lot of them. But I don't see as well now and would have mine set up if I knew someone good. But be warned, there are "experts" who couldn't set up a folding chair. I well remember the customer who proudly brought in his table and told me a dealer had set it up with a distortion analyzer. I was suspicious and checked it with a cartaline [alignment protractor]. It was about as far out of alignment as it was possible to get. Nevertheless, the customer forbade me to touch it on the grounds that I didn't have a distortion analyzer. It was customers like this that who drove me to declare that if I ever opened another audio business I would call it PBS audio, from the Biblical Injunction, Cast , etc. If you want to do it yourself make sure you have the proper tools. With the protractors I use I find it helpful to use masking tape to fasten the platter in one place so you can't jog it while lowering the stylus onto the protractor, but more modern ones may not require this.
Ps The new VPI drive system is the ultimate extension to the idler principal in that it drives the OUTSIDE of the platter instead of the inside and can therefore use a much larger drive wheel. I am again becoming an audio dealer and intend to try one of them eventually. As to VTA, in the old days what was considered the most important thing was stylus rake angle [SRA] the best results were usually achieved with the arm slightly lower on the pivot side than the stylus side. But all tracking angles are a compromise. It will vary between records. The best thing about arms like the Lustre 801 or the top VPI arms is that they can be easily adjusted while the record is playing. My SME iv will do this too, but not as well.
