more or less. Its a cheap rubber mat on top of a cheap felt mat. By themselves neither allows proper VTA with anything I own. I have never gotten around to buying a proper techincs mat to make it work right. UPDATE! I remembered that I had an oracle mat that I got with some other gear. Tried it out. fucking mats. GRRR. I wish that I could not hear a difference. It would make my life sooooooo much simpler. you people in this thread are a bad influence on my wallet.

They were sold to someone who blew them up. Kudos to Jim for taking them back and avoiding a scene even though it probably cost him a bunch of money. link to FS thread with more details. I stand behind my guess for long term high DC offset. the RS-60 can lift a buisness card with low bass. Lay the RS-60 on a table flat, with a buisness card covering the port. Play a 40-60hz tone (or just play the first minute of prodigy "smack my bitch up") reallllllllly loud. If the buisness card did not lift off of the headphone you are not trying hard enough. Pray anyone cohabiting your residence does not come looking for your new speakers... Sorry I didnt take photos of the insides of the RS-60 but my camera at the time could have sucked a golf ball through a garden hose, except it would probably have failed at that too. They look pretty much like any other brown headband RS-1 from the outside, but do have a touch of cool on the insides. The drivers are still not glued in and should just shake out after pulling the pads off. Maybe push the cable into the cup an inch or 2 too.

Click photo for a few more like it. Got the cartridge, headshell, and clamp today out of the "old vinyl gear" bag at the local audio society holiday party.

Amp/DAC recommendation for D2000 & DT990
nikongod replied to rpaul's topic in Headphone Amplification
No melos? Why? I have posted my thoughts on this elsewhere on this site, and would recoemdn quite strongly against it. fixed it for you. sorry to maybe be the first to say to you that grado does not use the same crap cables as everyone else. Bummer. Sorry, I didnt read the rest of your post the first sentance had the essence of the rest in it for me. -
Amp/DAC recommendation for D2000 & DT990
nikongod replied to rpaul's topic in Headphone Amplification
I do still like the "SP Sound" quite a bit. If you are comfy checking the amp over a bit they do make an excellent option. If you are comfy DIY'ing the amp, finding an MPX3/PPX3 is as easy as posting a WTB for $25 more than what the last one sold for, which wasn't much. -
sounds good to me. Like everyone else Im upgrading to JH13

It means that the transformer is "floated" (not grounded) as opposed to grounded. Transformers were historically ALWAYS grounded somewhere so that heaven forbid the insulation in the transformer fails any voltage that finds its way out of where you want it goes straight to ground. Newer transformers make failures far less likely with better materials and construction techniques, but for historical reference. The problems with center tapping the transformer come at you from a few directions. The first is that the center tap is not always perfectly centered on the windings so the 2 phases are not always equal in every respect and not as well balanced as they could be. Better transformers avoid this with better construction, but thats $$$$. The second is that switching from "balanced" to "single ended" with a center tapped transformer requires yet another switch which must be switched properly (if you float the transformer its very easy to hook up to SE). The last thing is that by grounding the transformers you have introduced "ground" into the signal path where you are going from component to component: no ground connections between components=no ground loops! Going back to the telephone example or long runs of cable like at a concert, ground loops become very dificult to deal with any other way when dealing with stuff that is being run on different power grids. By floating, the balance is set by the load to ground which can be controlled far more accurately than a center tap. In the case of stuff that is not grounded (headphones, speakers, the output/input transformers in audio components, etc) there is no ground connection at all, and the balance is set by random looses. This random junk is actually MUCH better than it would seem to be as it effects EVERYTHING equally. Balanced is no longer balanced when the 2 phases are not equal in every respect. As a quick example of floating, I have run an MC cartridge into an MC SUT fully floated without shields and gotten acceptable noise pickup (it was barely audible, but a somewhat contrived test: I have heard noisier things set up "right") . no shield, 0.3mv signal. It is better with a shield but Now that all of that is out there, Im not convinced floating/grounding the transformer matters either way for SQ on the output of a POWER amplifier except in providing certain types of feedback, which is not an issue here. I have heard some arguments for noise getting into the system through the outputs, but that seems to be more of a problem for amps with global feedback loops than open loop amps.

happy late birthday.

Taking the shell off is pretty easy. The key is making sure you separate all the joints with the exact-o knife and ROTATING the cartridge in & out of the shell, not lifting it straight up. It requires surprisingly little force once you separate the joints.

The Denon is now all glued together, I drilled some holes in the stock body, and stuck some dynomat in the few places I think it will fit. Im going to put the ventilated stock body shell back on to see how that works out. PS: I really want a macro lens
