I used to have LCD-2 and HE-6 planars back in a day, used them with Beta22 amplifier and Audio-gd Reference-8 DAC (PCM1704). They were great, but sometimes they seemed to lack something what was in dynamic headphones, like HD600 or T1. They can sound too technically, especially the bass. Because of this, and also because of the almost always heavy weight and high amplification requirements, I didn’t consider planars anymore. For some time now, only headphones lighter than 300 grams are comfortable for me, and the HD660S pleased me with both comfort and versatile sound (I bought them to replace Fostex X00 ebony). Both moderate brightness and good bass were important, as I listened to rock a lot. However, sometimes reading different feedbacks and reviews, there was a desire to try TOTL again, but a dynamic one. Choosing by weight, the Beyerdynamic T1-2 might have been an almost fit, but they still had a rather emphasized peak at 8 kHz, which I immediately noticed in the store. Also the HD800S could be considered as an option, but I tried the original HD800 before and didn’t quite like their too distant and lightweight presentation, like I was sitting in a big room. According to reviews, Focal Clear were very interesting, but alas they are too heavy.
So one day I became interested in the ADX5000 after reading forum member’s reviews, whose opinion I can trust, but then the desire was beaten off by too high price and mixed reviews of other owners. However, the moment came when I saw a good review on reddit from someone with quite similar musical tastes, and at the same time, an offer appeared at a very good price! So I decided that until I myself tried those headphones for a long time at home, I couldn’t make a complete impression. The purchase was blind, but I guess since I studied the reviews for a long time, the purchase turned out to be very successful. Yes, these are not the most linear headphones, but their special tuning is to my liking and can easily cheer me up. Another interesting aspect of these headphones seemed to me that they can be easily listened as a background, but if you wish, you can immerse yourself in the music at any moment.
Now I feel like I can hear the limit of my system, but there is more room to grow if I want to and the headphones can open up even better. In fact, I’m already intrigued by the Cayin HA-3A amp, which has just been released, has a very good Headfonia review. It’s not OTL, so probably not the best choice, but I have similar as in review impressions from my own amplifier, which also used JJ tubes by default.
