@b_limo,
yes, moving away from this $1200 amp thread to a DAC thread makes sense..Those other Node2i links above may only be helpful if you choose to add-on a DAC and bypass your internal DAC in the Bluesound Node2i.
FYI: In the Node2i, and other Gen2 products in that line, they moved from a Cirrus Logic DAC to a Burr Brown 24/192 DAC chipset. Fairly close to same level of what you’ll find in other $500-700 DACs you want to replace it with - likely more of a lateral move again.
Now if you step up to one of the better MHDT non-over-sampling (NOS) "R2R Ladder" Orchid dacs, or an upper Pagoda dac, or maybe an upper Schitt DAC, or go for it with a Denefrips R2R dac - maybe find one used or on sale, would be worth the jump. Some people are true audio nuts and upgrade DACS every year, buy their high $ hand me down. That’s why I keep my streamer separate from my DAC.
Some people will tell you moving to a super-upgraded DAC is, quote "the single best investment they ever made in their system", because it benefits all other downstream components, preamps, amps, speakers, final music result! Fasten your seatbelt for best-DAC feedback!
Various on this thread had some good ideas for ya too. Don’t forget, it all starts with the source and trickles downhill from there. Good Luck.
