A New Take on the Classic Pass Labs D1 with an ESS Dac

[avbuilder]

Can you guide me to the link were the upper chassis is available for 50 dollars.

The link below will show you hundreds of China made chasis. Although all information are in Chinese, you can see the photo and price in RMB. If you need help on translation or even order it, drop me a PM and I will try my best to help.

The chasis is very heavy 6-15kg, the shipping will be more expensive.

I'm secretly hoping a few people in this group want to do a nice chassis for this, as mine is still a mess of wires sitting in the back of my stereo rack. I have a design, I just don't want to spend the money on a one-off chassis like that.

indeed mate, I cant believe i'm even considering getting that matching rig out, its like i'm watching myself in a car crash from outside. I even told hochopeper to slap me if he saw me considering it.

i'd be interested in the chassis perhaps, but probably my build requirements wont mesh with yours, I have 2 dacs in a dual stereo balanced setup, plus Ian's fifo, plus titan, 4 channel output, plus combined 2 channel headphone source output, MCU plus 1 or 2 xbee's and ideally a retro-ish LCD with wifi/ipad remote.

mostly external prereg and transformers with the only AC entering the case going to the NTD1 regs unless I bypass their bridges, which I might actually do just to keep it 'simple' the case would have to be a monster to fit it all in one so it would be a 2 box with DC umbilical with cannons

Will this China made chasis meet your requirement, only cost $50. All alumimum including heat sink at both side.

not a chance for me

They have huge size chassis which can accommodate all your parts. Some even has the PASS logo on the front panel

in that case they arent getting a cent of my money! besides I dont want a huge poweramp case, I still want it to look like a dac and most of the heatsinks on these cases are not terribly useful, there needs to be a way to couple the floor very well thermally to the floor. no I think the case needs to be purpose built and I really dont approve of theft of intellectual property; so dont care how cheap they are and using a company that fakes Papas logo for cases to accommodate a dac IV design originally freely given by papa would be in very bad taste.

sorry but this sort of thing does not sit well with me at all

Totally agree, I would buy any chassis with logo. Looking forward to see your finish chassis.

cool, glad you are on the same page

you may be waiting a while, as I had just about totally decided against using the D1 for my other channels, not because I dont like it, but because its such a space hog and really requires a custom heatsink, or a custom chassis to do properly even with 1 of them, but ive not been able to find another design I like as much, the build except for the second D1 and the control systems is all working on the bench, but arranging everything optimally and financing the custom case will take some time. probably the PSU case will just be made from T6 alloy channel and plate and kept out of sight, but I guess its time to start modelling up the dac chassis.

Your progress is much better than me, I am still waiting for the delivery of BIII and the next GB for the NTD1 PCB. The only component ready is Ian's FIFO. Still a long way to go before thinking about the chassis.

yeah I have 1 x AKD12P + titan + D1 in a case (with the lid off to enable my constant tweaking) and a second AKD12P on the bench with fifo and with opc's BAL-BAL 'the wire' headphone amp connected directly acting as a buffered IV stage that can drive headphones (spectacularly well I might add Owen and it doesnt make a bad IV stage either)

so putting basically double the below plus MCU, display and control systems into one case I think would make it impossible to have a clean layout. much easier (though still not easy) to do it with 2

actually I tell a lie, for the moment I have a buffalo II in with the NTD1 while other experiments are ongoing
