I'll be offering bare PCBs, completely assembled PCBs, and likely a fully assembled product style version.

Stay tuned here for a link in the coming weeks.

Subscribing to the thread. Please post here first when you have some more kits or complete amps for sale.

good news that there's to be more bits in the offering. It'd be gready of me to get more amps, however I'm certainly intrested in a DAC and am keeping a little aside just in case

Hi Guys,

Glad to hear the enthusiastic comments! As expected, all of this is a little more work than I anticipated, but things are progressing. I'm working on a website as we speak, and some board orders are starting to trickle in. I should know more in the next week or two.

Thanks for all the patience with this, and I'll be sure to let everyone know as soon as I'm ready to get things started

Cheers,
Owen

Nothing wrong with being greedy! If you get a new DAC, you'll almost certainly find yourself justifying the 'need' for a balanced input on your amps

It's not greedy when it is a necessity!!


No matter what, you'll have less amps than qusp :P

LOL ... does anyone have more amps the qusp???

Was thinking the very same thing about balanced inputs. If a DAC is to offered, then surely it'll be ballanced output giving the need for a balanced headphone amp to match it. Furthermore, a second balanced unit to act as a pre-amp for the Power Amp, which can be simply changed into recieving a balanced input. Conluding, 1 x dac and 2 x bal-bal amps ... No pressure Owen

what makes you think you need a preamp? better to just install a decent ADC in front of the dac IMO.

haha you need look no further than the pages of the Pass Labs forum to find people with many more amps than I

Can I have a silly question about the balanced wire amps ?

Can I use it in SE mode ?, like at the balanced DACs ? I mean only using the positive half of each channel ? I know that you can use the balanced bridged amps like that, like the headamp GS-X.

You certainly could, but you may need to solder a 10k resistor in parallel with the cap on the VCOM pin to ensure the output common mode voltage is 0.

If you do that, then there's no reason you can't take a single phase of the output (with reference to GND) to drive a pair of headphones.

You should definitely not ground the unused output however, as that would be the equivalent to a dead short for the buffer.

This arrangement will have higher distortion and noise, so I would instead suggest the use of a BAL-SE or SE-SE amp

Cheers,
Owen
