Hi, this is just a section to show product information and fun pictures. Thanks for looking

This is me along with my new friend Iza at a friend/customers€‹ house.

This is part of the power supply, note the PI filter with Mundorf M-lytic capacitors and 12ga. copper foil chokes. If you look carefully you will see the bridge rectifier in between the transformers (2 transformers in every mono amp, reduces impedance and gives more power and impact) and capacitors. 16 Schottky diodes (lowest switching noise of any diode period) in quad groups to lower impedance. No one else has even thought about stuff like this although it should be standard in any amplifier trying to make a statement for absolute best. Click on image to enlarge.

Paradox Pulse 30db phono gain stage

This customer is into vintage McIntosh equipment.

See the Paradox Pulse chassis to the right.

He needed an extra gain stage for his Pulse Guard R mc cartridge.

This unit is battery powered JFET with adjustable loading.

If you need something special for your system give us a call.

Making the best in custom products is also what we do.

Paradox Pulse products being tested!
This is a photo from a dealer putting the Pulse cables and amplifiers to the test.

Note the Focal speakers and MYTEK DAC, not my choice but good gear non the less.

Customers picture

The pictures were taken by a customer that purchased the Abis SA1.2 tonearm with Cardas modifications along with adapter box and interconnect.
A miss hap led to a second cartridge and he sent videos of both so I thought I would share.
Note different video for each picture, click on picture then  go to link.
He is now going to do a second arm and cartridge for mono.
This was the first of many of the battery powered phono. Easy to use, any AA batteries will work and 8 recharable will provide you with about one month of 24 hour constant operation. The 9 volt batteries in the picture were used in the original testing. I use the same chassis, circuit board and parts as my standard phono pre I just get to save many hundreds of dollars on the double regulated power supply.
FET (matched gain so channels are the same) and cap are all that is in the signal path besides wire and connector for 30db of quite clean and clear gain. There are RCA's on the outside for adjustable loading at any time. Now there is no reason to use an SUT with their many compromises (the least of which is that you cannot load the cartridge properly as the SUT is the load for the cartridge) and distortions. Read this link if you are in doubt of what I say.


Just another day at Paradox

Like everything else Paradox builds its one at a time.
I laid out a few of my different end caps showing the clear and black anodizing.
The front caps are all the same (except pre-amp still to come) Paradox Pulse but you can see the different back caps USB DAC, Phono and Amplifier in the picture.
The two boards will be used with battery power, the first one is 70db of MC/RIAA gain and the second is another 30db gain for using with a MM phono pre.

Customer playback

A very beautiful playback front end and I am grateful that he choose a Pulse cartridge.
I think this is the 'Red Baron' from the Testimonials/Awards page.

Yes a RB 300

This RB 300 has been re-wired with Cardas phono wire, modified bearings and has aftermarket Michell Tecno counterweights so that all cartridges (including mine) can be used.
I know the picture dose not show the cartridge but a Pulse R Boron with 40 pieces of lead shot is whats up front, yummy.
The turntable is a heavily modified Lenco screwed to a 75 pound custom plinth via 1/8" lead sheet contact pads. Aftermarket brass bearing housing with twin nitrated ceramic balls standing end to end for the spindle bearing, stacked platters with a SDS (I sell his products now) in between platters suede/suede leather mat for record interface.
I did not even start to talk about the mods underneath which are extensive for both motor and idler drive.

Pulse 3 with Boron

Boron cantilever and nude line contact diamond.
I used this cartridge and a Pulse R with Boron in a shoot out and the Pulse R is the winner sorry Pulse 3. Pardon the dust and hairs on the cartridge, I did not see them with my naked eye before I took the picture.
Both cartridges were subjected to several different records and loads with the R having 680 as our favorite load, the 3 liked 680 ohms also but performed a little better at 400 ohms.

We now use a Sapphire cantilever and Micro Ridge (SMR) diamond as our favorite expression of the Denon 103R, and yes we prefer the R to the 3.

Pulse Turntable base

The holes in the bottom are filled with a slurry of lead shot and contact cement. There is a combination of 1" and 1.5" holes when the holes are finished a truck bed liner is sprayed on for added damping and sound absorption.
Multiple layers of Baltic Birch make up the base plinth.
There are threaded inserts towards the front corners the back only having one in the center, it is so much easier leveling with 3 legs.

Paradox LP-240

The LP-240 stands for Line source Point source and the 240 for square inches of radiating surface.
This Planar Magnetic Satellite speaker was built over 30 years ago by Paradox Speakers they still work but are not usable as the efficiency of the ceramic magnets is all but gone.
Don't mind the work area behind them it always looks like that!
My brother and I have been doing crazy stuff for almost 40 years. He built both of these speakers (the Blackheart also) by the way.

Paradox Blackheart 

This is another 30 year old speaker that very few were sold, three I think.
The lower ones were the original prototypes using sand and plastic resin to make the enclosure.
The Blackheart used a combination of limestone (powdered rock) and plastic resin for its enclosuer and their stand is built out of 4" square steel tubing 1/4" thick, bottom plate 12"x12"x0.25".
The stand was an integral part of the speaker as the two had matching 3" holes so the speaker could only get down to 80hz and roll off so no cross-over was needed to keep the bass out of the satellite, just add sub-woofer.
The paint jobs were automotive black lacquer done by a guy that specialized in custom motorcycle work, each costing $200-. That was expensive in the 80's.
Both pair function properly to this day.

Modify anything and make it better!

Many customers (this one being the best so far) are asking can I modify my yada yada yada cartridge and I answer honestly, I don't know!
I give the dimension specifications for the Universal body so you can measure and determine for yourself what can be done.
Here are the dimensions for the DIY;
Weight 6 grams, 
Outside; 0.724" width x 0.949" length x 0.43" high
Inside; 0.477" x 0.879" length x 0.363" high

NOT just for Denons anymore

Mounting area is .398" wide x .725" long x 0.11" deep. You can also attach to the outside dimensions (.725" wide x .8" long x .232" high) but would cover the screw holes making you adjust the screw height so as to not poke through to the cartridge.
Body weight 4.2 grams for body, add lead 4.5 grams, add stainless screws 5.5 grams total added weight less plastic body 0.8 grams, epoxy should be negligible.
Cartridge (SC35C) angle in stock body 13 degree, with lead support in Pulse body 12 degrees.
