you can do with 2 small signal relays with 2 poles. They are small and they can easily placed.
I see diyers favor takamisawa small signal relays. They are 2 poles as required. Their voltage varies with model number. 5V or 12V are the suitable voltages for dac project. You can easily find them at distributors or ebay like sites.
It seems suitable. You should discard screw terminals and solder wires directly to the terminal holes.
I have plenty of parts in my box, one of them is Nichicon Gold Tune, 35 v rated, but capacitance is 10000uF. Can I use it instead of the ones on dac, even if dac has 4700uF ?
I wonder how Dario managed to put those 30mm panasonic caps 😀 max diameter is 25 mm board can take without bending anything 😀
Well I understood that later 🙂
My board is a bit different to yours , version 1.2
Some caps are different.
I ll remove all bypasses, change smoothing caps and opamps for now.

actually dac plays very nice without mods pc usb dac , foobar used.
I wonder how music quality is going to improve, I hope new opamps+caps will give more "flesh" , otherwise I m satisfied anyway 🙂

You'll decide it at some point. For example, my concern is high detail with 3D holography. If one of stages in your chain is not doing really good, you'll maybe satisfied with tonal balance, detail etc. but you'll never get that magic holography.
Will see. So far amp is great, pre is transparent, dac playing well, speakers - nice monitors. Will see will see 🙂
My concern is to reproduce music as "natural" as possible.
Will never regret going diy route.

Opamp package is dip8 ?

Yes it is, should just drop right in.
Was going to suggest an lme49710ha, but the only ones I saw on the auction site were from France, and a bit pricey.
I would also replace the small caps in the feedback loop with some film/foil. I found some surplus Wima fpk that made a big difference in how any op amp sounds.
