About 4 years ago I was willing to spend up to $2k or more for a headphone upgrade over my Grado RS1. I was convinced that the Audeze LCDX or LCD3 was what I wanted. I went to a local dealer that had a very neat headphone nook with several headphone amps and all the Audeze headphones there for audition. I was very exited and fully expecting to bring home a pair that day. When I heard the LCD3 and LCDX they were amazingly better than my Grados when it comes to deep bass extension. And it was not just bass quantity but also excellent quality. However as they increased in frequency their qualities decreased. The mids and highs were simply not as detailed and insightful as my Grado RS1. Nor did sound as alive as my Grados. So despite the RS1 faults and the fact that the Audeze performed much better in some ways. I was not about to spend that much money on a pair of headphones that did not have the detail in the mids and highs I was accustomed to. This lead me to audition the HD800S and I knew I had found my upgrade. Now the HD800S do not have the incredible sub bass of the LCD3 but when it comes to about everything else, staging detail timbre, the HD800S are better IHMO. I also found the LCD headphones heavy and uncomfortable leaving the top of my head sore. For me the HD800S are good all rounders and excel with orchestral music and much to my surprise progressive rock. My Grado RS1s excel with small ensemble acoustic music. I do not like them as much for orchestra or even progressive rock. I find they get congested when things get too complicated. I have not heard some of the pricier Grados like the GS3000 but it would not surprise me if they held their own in their price range. Some reviews indicate they are amazing. I do now know that before I get a new pair of Grados that I need to try the TTVJ pads on my current ones first. Perhaps they will make them more than a niche headphone for small ensemble acoustic in my collection. My Dad has a pair of Senn 650 and when I heard them I finally understood what is meant by the Senn veil with these. While they have their merits I would rather listen to a pair the much cheaper Grado SR80 out of a portable DAP any day of the week. But that is just based on my personal listening preference. That said I know some when they get the 650 paired with the right amp it fits their listening preference like a glove. And I consider them blessed. Mini Rant: So if some of you do not understand the appeal of Grados I get it. But to run them down in such a crude manner reveals your ignorance and lack of respect.
