Time for an update on the MA-90... or what ever I'm going to call this thing. This is prototype nr.2 and it seemed only fitting to put on the "Orpheus" IQ stand: So what's new, well the headband is now fully DIY with just the arc being borrowed off a Senn HD58x but they are all the same and very close to the HE90 arc in design. Then a custom adapter block in the HE90 style adapts it to the forks... which didn't come out quite right. A bit too long and too thick to bend correctly so I'll have to redesign them but no big issue there. The actual housing is mostly complete at this point but the biggest hurdle were the metal backs, or so I thought: In the end, pretty simple and I can mass produce them by hand in quick order. I've made about 20 of them at this point and they fit snugly in there, no glue needed at all. Inside there is a new baffle, new spacers and new stators but they will need further work. Mostly I have to move the contacts to better fit inside the housing and those are ready to be made. This set is fitted with the cheap Chinese Solitaire earpads and sound pretty good with them. They are 15$ shipped compared to the HE90 pads which are impossible to get at this point.

The new comment editing widget and I do not get a long, which makes sense as I didn't get along with the old one either. What I'm talking about with the EF 50mm F/1.4 and IR 5D:

Funny enough I listed to the following about an hour ago... EDIT: Might as well add...

Wow, those look great. I'd love a pair as I only have the one real set to play with.

Very nice! I happened to have some ear pads made locally, and they come out to be pretty close to HE90’s. I can send you a pair if you like. 😁

Thread resurrection and last 60 days of damage. Work bonus and too much time on eBay represented. Will now slow down.

There are so many variables. When I say favorite guitar players, I'm asking for your personal favorites, not who's better than whoever. I'm also not asking as some sort of silly debate. I'm asking to discover new music myself.

I'd give them high praise if they used a more relevant leaf for the background of their PCB photos. They also missed an opportunity to use 420(unit) parts in every possible location. A 420pf cap could even be pronounced as "puffs". This makes me sad. I strongly dislike how they/you used the transformer hold-down bolt for your IEC ground. It can create a shorted turn in the wrong conditions. Give it its own screw, or use one of the screws to hold the IEC socket in. What is with the heatsinks in your last photo? Discrete opamp?

HE90 "clone" first prototypes up and running as of yesterday: The drivers are all PCB based with 2um mylar diaphragms. They are about 3mm lower in height than stock to accommodate the cable entry and move the connections to the bottom of the drivers. The housing is resin 3D printed but this is the old version which has now been abandoned for a new one that has yet to arrive. Cables are King Sound (as I had some in stock) and allow me to fit it all in the same housing size as the original. The earpads are ones for the T+A Solitaire that are not a great fit but dirt cheap... so work just fine for this role. I've ordered new genuine pads but I'm not sure if Senn have any in stock. Next up is to refine the headband design and start to work on prototyping the metal back shell. Now I just wait on parts as usual... As for the sound, far from finished, even in prototype form but a HE90 with actual bass response... perish the thought!! ;)
