The "Frivolous DIY" Thread
« on: June 04, 2012, 09:42:07 PM »

Post your marginally significant mods here.

Here is my HD 650 replacement cable that I bought for my HD 424X early this year.  Superior cable to stock: a lot less stiff, feels nice, sound opened up immensely compared to the steel conductors that were on the HD 424X for the past two or so decades.  Better molded plastic connectors downstream too.

Recently I put a 4-pin XLR on it because my amp puts out significantly more power (for this headphone, namely voltage) in balanced mode.  Haven't tried it out yet though.

Today I put some red heat shrink on the right side (I hope!) connector.  Frivolous mod.  Satisfaction factor of 10x.

Hey Don you should post pics of some of your past amp builds somewhere on this forum sometime.  If you want.  I remember many of them looking really awesome.

I have something better for this thread ;-)

I am guessing there are all sorts of levels of frivolous , to me this falls into that domain as it is not making a product from naught but tweaking something to suite the needs of the end user.

LFF had put out a call for help a while back to mod his Musical Fidelity XA-1 for headphone use.

I am glad I sent him a pm as it has enabled me to get to know one of the great folk in this hobby and that is what this community is all about. We started off with a pretty (grubby :p ) stock XA-1.



After a little back and forth it was decided to maul the front panel and forego the option of "return to stock" should this end up in epic fail.





The tape monitor switch removed to make space in that section of the amp.



Somewhere along the ways LFF decided that an internal DAC might be a nice touch

so the tape in and loop out RCA's were removed



and the dac was dropped into place



and that left us with the morphed XA-1



XLR and TRS output jacks with a switchable output for speakers or headphones through a resistor network

small details not visible are an led indicator to tell you that the dac is plugged in ( just below the selector ) and relocated the power led to the bottom of the front panel.

The rear panel now has a usb input for the dac and a 3.5mm jack to loop out the dac in case you want to use it for anything else.



I switched the black screws to the front intentionally as I liked the aesthetic, LFF is of course free to switch em back.

and so ends a frivolous tale of LFF's XA-1


It has not yet been put into service as I am waiting on a small usb cable with dual right angle connectors ( only way it would fit )  - hopefully in the week and then LFF will have to give us his feedback

Ummm...not sure how frivolous that was.  You might be violating the terms of service being that constructive.   :P

Great work on the MF amp Don. A question for you if you don't mind. I have seen one of your "2 story" amps posted on HC which had windows looking into the amp; I loved the look of it. Any suggestions on how to do this? I tried drilling a screw hole in a sheet of plexi I picked up at home depot and managed to get 1 hole done successfully amidst 3 failed ones (all cracked  :'( )

Thanks

edit: I think my question is what's the best way to mount it to a metal panel? (not very thick, guessing 2 mm, maybe 3 mm)
