Thanks, I'm still considering what to do.
Honestly, I like less buttons!
Most of iFi's products seem too "gimmicky" with all the filters, eq's settings. etc. I'm one of those that doesn't use or believe in EQ. It either sounds right or it doesn't.
If not, move on to something that does.
Same applies with the new Mojo, too many settings which seem unnecessary.
I can tell you what everything on the BL does, there is 3d which to me is a gimmick, hard to tell a difference, on the opposite hand there are people who love it and swear by it, there is also polarity, similar but "more subtle" iFi even notes it should sound the same, to me it does not, infact sometimes reverse polarity sounds better but I still don't touch it..... Now the DAC settings, are nice IMO, it basically decides how analytical vs smooth the amp gets, I am not sure I would say there are so much increases in music but it's VERY useful IMO for harsh music or movies, so that I do like and consider useful (note here I ALSO don't like EQ< but simply for the reason I like manual switches if I have to switch a headphone every time, I am a driver so for me that is actually fun, switching some PC program, I am also am somewhat of programmer lol.... maybe that is the reason not so much anymore, switching on PC is boring, lame and annoying, I know I can make it easy but I just don't like it....)
Anyway last one is bass switch, I actually love this, I also love bass, I don't want to EQ it in, and also for using my BL as a pre-amp for tubes super useful. Hardware EQ is a bit different than software, and IMO this is the best application it's 10db at 20Hz and goes down fast to around 250Hz, so it doesn't as much make huge difference to the initial punch but it very much improves the physicality of the bass.....
For me again, hate EQ, refuse to use it, consider many of the switches and setting on amp useless...
I do find a lot of utility and use from the DAC setting button (also this one doesn't feel gimmicky, like the 3D which does something besides what is label to fake something)
and I find a lot of utility with bass as I like it
I have to add in again, when using different headphones that DAC switch can be the difference between too much and not enough for the treble, the same can be said for the bass..... I really have to strongly voice my love of those two here, and
that is why I will never sell the iFi Micro BL unless I have something that can do what it does in those 2 buttons!
The mojo's switches are beyond useless to me, but it's size is why I keep it, GOAT good sounding small amp.
