I am such a noob! I'm close to 2 years using my E2 and I literally just read this hour about using clean usb power
Looks like I have 4 options from cheapest to most expensive:
1) powered Amazon basics USB hub
2) Audioquest Jitterbug
3) some Wyrd Schiit
4) USB REGEN
Anyone here use Audioquest Jitterbug? I use my E2 for my desktop and also bring it to work everyday, so the Jitterbug seems like my best bet considering I can also use it on top of Wyrd or REGEN if I upgrade even further in the future (at least from what I read). Most of the info I found points to positive benefits for the E2 minus a few saying it's better without it.
I'm also using some cheapo 6 inch USB cable. Not sure if it makes any difference? Perhaps it may because I bought this $7 2 feet audio cable from ebay for my D600 and the sound did get worse (to my big surprise!). Any recommendations on a quality cable for the E2? I'll give it a try.
EDIT: Can people with no MQA-enabled device play Master quality songs from Tidal? My E2 is not updated, but somehow Tidal detects it as MQA-enabled and I can play Master. I do notice slight improvement from HiFi quality.
EDIT2: I also have MQA passthrough enabled.
EDIT3: My E2 is not updated because I get an error. My device was bought on ebay, apparently from someone who stole it from Meridian hence my serial code is blacklisted t.t
