CLEANING YOUR CARTRIDGE

We only recommend the sticky type of stylus cleaners. They are reusable after washing with soap and water and clean without harsh chemicals like alcohol. My favorite is MOONGEL damper pads. They are used in pro audio for drumhead damping but work great as a stylus cleaner. Under $10- per 6 pack. Just lower cartridge onto pad and lift,  you can do it several times if need be just move the cartridge to a clean portion.
The other product we use and recommend is LAST stylast treatment, it has a big 5 on the side of the bottle. This is brushed onto your stylus after cleaning. Last has other products like cleaner but I will not recommend any cleaner with alcohol in it and most liquids have alcohol.
Be sure to clean your records also. I favor the sonic type which can be purchased for as little as $500- on ebay.

The Pulse Guard

The Pulse Guard R SMR

All of Paradox aluminum products are made in America, machined in America and finished in America.
This is something that we are very proud of. The quality of material and workmanship in every chassis and cartridge body we build is second to none.

The Paradox Pulse Guard body is the pinnacle of bodies for the Denon 103 series of moving coil cartridges. Yes this body will fit any of the 103's like the R, Gold, Pro, SL, C1, D, FL, GL (4N High Purity Gold Wire Coils 99.99%), LC, LCII, M, S, SA, U and the DL 104. As far as any of the other Denon and other cartridges I don't know!
I can (at your risk) take your cartridge apart (I did this with a Hana MC cartridge and put it in a Universal body and it still works) and fit it into one of my Pulse bodies, but it will cost a minimum of $100- for the work along the cost of a body, and if I break it I am NOT responsible for a replacement. This is at your risk type of work.
The cost of trying new things, sometimes it works (I have not broke a customers cartridge yet, but there is always a first) other times not so well.

The best modification you can buy for the 103 series

A brief tutorial of how the Pulse cartridge bodies are built. 
First the billet T-6 aluminum material (USA made) used is much larger than the end product, as every part is machined out of the billet so there is no side that is not milled. Milling also done in USA
After the milling process the material is then sent out for hard anodizing, yes in America. Once it is returned to the machine shop it is then chucked back up for the finishing work which is all milled through the hard anodizing, no laser etching here. The finished look says it all as bare aluminum makes the Pulse logo and bridge for visibility of the stylus. There is typically a 10% loss of bodies during all the processes. The threaded aluminum is 3-56 threads and I provide SS and Brass screws. Of course the factory plastic guard will still fit, how do you think I came up with the name for the GUARD body in the first place.
All of my Pulse bodies come with lead for internal damping of resonations for that natural sound but the Guard body takes it much further with 6 vertical holes that accommodate 20 pieces of lead shot and epoxy.
I have to pre install the perimeter lead and epoxy which is very time consuming I cannot do more than 3 per batch of epoxy and my epoxy takes 2 hours to set up although it starts to thicken after 30 minutes.
The Epoxy I use is an electronic type that is low viscosity, so it can run into all the nooks crannies and holes, if it is thick like honey it may not flow everywhere properly.
We have several other MC cartridges to include Miyajima Laboratory Shilabe, and Benz Micro LP S just to name two and yes they are a little better than the Pulse Guard R SMR cartridge, but not as much better as you would think. If I were to give a number rating for the performance of a cartridge the Shilabe and LP S would get a 10 out of 10 and the Guard R SMR and Benz Gullwing SLR would get a 8 out of 10 rating. In the world of GREAT MC cartridges the Paradox Pulse Guard steps right up to the front of the pack.
I do not have a large mark up for the work and machine time that is involved in building the Guard body. So even though there are cheaper alternatives (I even have the DIY body which is superior to the ZOO) the Guard will provide you with a vastly superior product for your Denon MC modification.
Yes, other manufactures bodies will improve the stock sound of a 103, but wood bodies resonate with an assortment flavors and you want a non-resonating neutral body for your 103 series cartridge. Other metal bodies are not much better as they resonate with a different flavor just gluing them in and leaving the body exposed. There is also a lot of plastic left on a 103 when you "press in", this distortion filled cancer must be eliminated. No other body will eliminate resonations or outperform the Pulse Guard body period. Enjoy

Paradox introduces the new Pulse line of electronics and cartridges.

I am told regularly that the Pulse cartridge is to heavy for my tone arm.
WHAT!!!
All you need is a heavier counter weight for that tone arm.
All tone arms can handle this cartridge easily.
