Win 11. Want to transfer music files. Manual says can be used as a reader but gives no specifics. It doesn't show up on the computer at all. You would figure plug and play as a reader.

USB to computer, I don't see the 220. I want to copy all music files to a folder for backup. What am I missing? Never tried to move files before.

Hi guys, Been out of the listening phase for a while now. Going thru some of my stuff the last few weeks and ran across my DAP and MP3 gear and some of my IEM/buds. Charged my DX220 and my xduoo X20 and started some listening. Didn't realise how much I missed all the listening pleasure, As a...

Found it. Thanks guys.

Not available on web site. I checked.

Hi guys Been a while since I've been here. Need manual for the 220. Checked ibasso site and it is not available. Had it in pdf on other computer that crashed last year and took a lot of info I had downloaded with it. Anyone have a copy I can get from them? Need to reset my time but I can't...

Haven't got that far yet to try making board with a buffer circuit, yet... Having fun with this.

Low impedance iem's will be pushing it with some opamps. Ensure enough power with high impedance Will only be running 1-9v batt Just to ensure enough power on the rails.

Working on a CMOY with 1 or 2 TLE2426 rail splitters. Have to get the size down some and do a mock-up

The wide board is 50 X 30mm (2 X 1-1/4 inch) Smaller board is 37 X 35mm (1-1/2 X 1-7/16inch)

Completed boards. Still need to do pot/jacks hookup to test operation.

This is what I came up with so far: Mock up: Etched E

That looks nice. Looking for something I can self-etch. Never tried to etch a double sided design yet. Working (trying to) on a couple simple single sided designs. Have you priced having those boards made?

Thanks, I'll check them out.

Hi, What are the pros and cons of driving the opamp to class A. Do different opamps require different value resistors for constant output current? What can I expect from doing this?

Well, after trying for hours trying to convert the schematic to PCB in DipTrace and not having any luck, I decided to do a "pad and trace" design. This is what I came up with:::: Board 38mmX35mm (about 1 1/2 inch by 1 3/8 inch) Extra pad for C1 is for larger caps if so inclined. Same for C2...

I looked at several sites, nothing inspired me, Some strange layouts, boards are a lot bigger than the size of Tangents. I built 3 following Tangent's layout. Would like to get PCB's following layout and size from Tangent's build guide. Used DipTrace to make schematic, but when I try...

Ebay seller ec2buy. They are in Walton Ky. From order to arrival took 4 days.

Anybody have these??

Looking for ready-to-etch file for cmoy amp PCB. Looked at PCB ARTIST but looks like a steep learning curve. Resistor divider virtual ground circuit and also using the TLE2426 if I can get both. Any format but PDF file would be ideal for proper scaling. I built a couple using the Tangent...

Old thread but..... Been listening to my Z2 (new) for a few weeks now and probably have about 200hrs on it. Sounded real good right out of the box. Sounds great now with some time on it. Have had no problems whatsoever with it. I replaced the 2 output caps which were 100uf 16v Nichicon FW...

Hi, Anyone have stripboard patterns/layout info for building a CMOY amp. Checked a couple diy sites that use stripboard but couldn't find anything. ( eg..guitar fx layouts,....) Already built 2 proto-board CMOY's using Tangent's pages. Came out well. I have a bunch of the strip boards and...

I Bought this right after I last posted. Figured I'd take a chance on this. Bought 6/2 arrived 6/6. Fast!! Here are a few gut shots. Uses a HT97220 chip in a QFN16 package (Data sheet specs) 125mw @ 32ohm each channel THD+N .003 90db SNR 112db Uses a TC4056A lipo charge chip Charge program...

I cant find a model or name anywhere. Wish I could see the inside. Anyone provide a gut-shot?
