@marco777 What do you mean by a little more open? If you mean more air and effortlessness, than I think the Gustard has a bit more air but the Pontus sounds a bit more relaxed to me. Not sure if this answers your question. Bass on R26 is tighter and punchier, but somehow I still prefer the Pontus even in this respect. It's just more full sounding. BTW, I've packed up the Gustard and sending back this weekend.
@soix Yes, I prefer the Aavik but to be honest I would be hard pressed to justify the extra cost. I hate to use the term, but the Aavik S-280 is a bit more 'analog' sounding. It's more relaxed and brings out the nuance in the music a bit better. Innuos has better clarity and definition but still has a hint of digital artifacts which I never knew existed until I heard the Aavik. The differences are noticeable but subtle. I do miss Sense 2.0 though ... definitely better sound quality than Roon.
