We can discuss here since we are talking about ideas for "new" DX260. Some people may not want tube amp card as only amp option, although could have same config as Nun or AMP16 allowing switch from tube to non-tube. AMP16 does not have LO. People may want that on new DX260. Current DX260 does not have replaceable amp cards. The DX240 did. Adding the ability to swap cards adds cost and if Ibasso has a ton of DX260 cases already made it would mean they could not be used. Would current size of DX260 have enough room for tube amp even? Check out AMP16 for example. If they did 1 bit DAC and added swap cards it would be so much like DX340 that it could eat into sales of DX340. They are going to have R2R in D17 later this year but not available yet and my guess they will have R2R/D17 based DAP likely as DX360 but that could be over a year before its out. I read somewhere that R2R is more expensive to make. Just putting in 1 bit DAC and keeping everything else the same except tuning would make "new" DX260 easy to make as they have the DAC, software etc. IT would just be a DX340 but without some of its more costly features and abilities to swap cards, DC12V In, battery bypass, separate amp/DAP battery, no SS case .. and they could tune it differently to have it not same as DX340. Replacement of CS DACs would make paying 2 times price of DX180 worth it for SQ. My guess is DX180 sells better than DX260. DX340 is selling like crazy. If they are just going to keep CS DACs with 665 SOC Android 13 it makes more sense to just not do a DX260 model until DX280 comes out ideally with 1 bit DAC. I owned both DX180 and DX260 at same time so could the difference between the 2. Amp section is a bit better on DX260 and micro details are better than DX180. 1 bit DAC there is a huge difference in SQ. It is an AWESOME DAC.
