Like someone else said look at the data sheet. I’m not gonna say the Daisy is like $3,000 mastering converter, but it sounds alright to me.
My opinion aside, here is the chip they use,
If you’re after true hi fidelity in guitar pedals though, I would be running only analog pedals with a 9-18v linear dc power supply. Well that is actually what I do. The 5V psu for my eurorack also has a 9 and 18V DC send out.
I have a TC electronic rack reverb that I could compare to the daisy’s reverb. But that would tell us very little.
I release music commercially and, I’m not name dropping I’m just trying to let you know that we come from a similar place of audio fidelity (and in my case maybe it’s a sort of paranoia )… I use a Dangerous AD+ and an Apogee Symphony for my studio I/O. So I’m not just like “eh it’s fine. Sounds just as good as my laptop speakers and scarlet interface.”
I don’t think you’ll be disappointed by it.
