Duet Mods

[Phil Leigh]

Since you're not too fond of power supply mods, would you say the same for the Bolder digital mods if an outboard DAC is used?

I'd be fond of PSU upgrades if they worked (ie improved the sound) - however as explained there is very little to be gained from simply upgrading the external supply without also re-arranging the internal PSU arrangements.

As for the Bolder Digital Mods... I couldn't possibly say, since I haven't heard them. I see that the top-end Bolder mods do address the internal PSU. I'm slightly bemused by the pricing of the "statement" mod that seems to revolve mostly around removing components (like nearly the whole analogue stage for example!) but hey-ho. I'm sure the ByBee quantum thingy is most of the cost.

Maybe someone who has a modded unit and a stock unit could do an AudioDiffMaker test on the digital output into the same DAC and see what happens? I'm pretty sure the analogue output sounds quite different...

I too would be very interested in the result...

Hi,

I have done a Receiver modification, actually it's really not a modification, more a upgrade of DAC section. I wanted to test the performance of the I2S digital audio output stream, too see if it was as good (or better) than a high-end CD-drive. I have made a board using high performance components and the result was clear, the Receiver is just as good a source as the CD-drive. The CD-drive I used was from the kit-company Daisy-Laser, http://www.daisy-laser.com/, which many high-end audio companies uses.

See more about my board here:

Also, thanks to everybody using this forum, I have been reading alot - and usually I can find answers to all my SB "challenges"
