When you said use a copper cable for the most musical tuning do you mean pure copper cable or the gold plated one because I for sure can’t afford a gold plated cable. Thank you.

LZ is HERE... and he's here to make you happy! Nice write up bud.

The ISN GC4 is a gold plated copper cable. But I have used some cheaper copper cables with some great results. No need to use a gold plated copper cable. My point in that particular segment is that the A7 can go beyond what is provided with aftermarket cables and tips.

There is a really great UPOCC copper cable that cost $40 on aliexpress that I use with my NM2+ Sounds great on the LZ A7 as well.

very nice write up bro, sidegrading h40 with a enhanced vocal presence and treble and less midbass, or maybe just a cleaner sound than h40. what would it be lz a7 or nm2+?

A7 is more versatile than the NM2+. That being said NM2+ is on a good sale right now on Drop. I like both for certain and both are different enough to get. But I would rate the A7 a bit higher end sonically than both earphones.

NM2+ with a good cable can sound right up there and is very comparative technically to even the A7. Go with what you can afford.

Do you think guitars are betters on the i3 or the lz a7?

A7 hands down.

LZ A7 does excellent with guitars. Better than the Tri I3 IMO.

Many, many thanks, sir!
