You know the Twin Pulse project with double-drive Grado?
it is a new prototype Spirit Labs that uses two drives connected in series. Load isobaric + resonance chamber. drive movements halved - piston movements faster and controlled mobile unit. in a very linear frequency response. warm sound and impressive dynamic at any volume.
load of 64 ohms easier for tube amps.
I do it in Italy with forum gazebo Audiofilo. if you like I can extend the tour for you,
Shipment to United States costs 50 € Twin Pulse I then every beta tester will send out to the next.
Lovely stuff, I recognise Adhi's handiwork. I saw his black rod blocks, but what's with your gimbals? - did you paint or anodise them yourself, or did Rholupat supply them in black? Never seen them on his website, and yours look extremely handsome ...
Grado RS-1i completely recabled with 20 feet of Cardas. The guy who did the recabling did a swell job of it but this is a mod that is not recommended for the average tinkerer. There is some risk that the wooden bodies will sustain damage in the ungluing and/or reassembly phase...
