I recently asked you guys for advice on getting good quality, easy fitting IEMs. One advice was to try the TRN V90's, another was to try different tips (e.g. spinfits) and/or cables.
It took a lot of reading and going back and forth. I was in doubt about getting easy fit TRN V90's, or the highly recommended LZ A6 minis with spinfit tips. In the end I pulled the trigger on the V90's with complementary "silver cable" because of the price. Then, late in the evening after a couple of beers, I did exactly what I had promised myself NOT to do and ordered the LZ A6 Mini's and spinfits as well.
I'm a newby and lack the vocabulary to properly describe the sound signature and quality, but here are my noob impressions after a few hours of listening.
TRN V90 - I like everything about them.
Out of the box there were an immediate easy fit with good seal and isolation with the stock tips. The sound is great. It is a little bit more bass heavy than my KZ ZSNs, but I think V90s are still considered balanced.
LZ A6 Mini
I was positively surprised by the V90's and full of anticipation for the highly rated LZ A6 mini's, but initially... they were dissappointing.
At first I couldn't figure out which IEM went where. They aren't marked left/right. The fit wasn't very good, a lot of twisting and turning to get seal and isolation, but even then they sounded thin, even distant.
I then put on the spinfit tips that I bought also. It was a big difference. Fitting them now is way less fiddly (although nowhere as easy as the V90's). The thin sound actually turned out to be very clear and multilayered and I felt more immersed in the music than I have experienced so far. A bit like the difference between looking at a monitor and VR goggles, although not that extreme. Maybe it's just my imagination because I paid more money for the A6 Mini's, but with the A6 mini's I have a tendency to "explore the sound", rather than just listening and enjoying my favorite music with the V90's. But I think I now understand what the term soundstage means.
I'm really happy with both purchases. The V90's for great sound and excellent fit out of the box. These will be my on the go IEMs.
The LZ A6 mini introduce me to a new level of performance, but I still need very much to get used to the mini's. It's still a bit of twisting and turning before they sit well. Once done the seal is great, but the sound isolation is less than with the V90's, meaning I need to sit in a more quiet area to really enjoy the sound they are able to produce.
I don't think I will buying new IEMs for a while. I need to go through my music library with both and understand what I'm listening at.
