First of all I need to write that 1266 TC are with me for about a month and LCD-4 are my main cans for almost two years. I'm still trying to determine what they are and probably will be for next few months. Now, after clearing that out I must say that the day before TC delivery I got Holo May and it changed my LCD-4's the way I didn't belive that DAC can. Because of this I even prefered to listen to Audeze more then the new thing for which I was waiting three months. It was creazy for me how magical, intimate, natural and real the Four's are with May. I gave some time for TC too though.oh you have a TC! How do you like it? How much do you use it vs your LCD-4? Do you find they complement each other or overlap? I was looking to buy a TC next week and I'd definitely appreciate your thoughts.
They are different because of soundstage scale. Bass is different, more opened (probably due to bigger soundstage), reminds me a speaker setup. Some details in the tracks pop more. Yet recessed mids can make some tracks not good (like Nine Inch Nails Hurt, Queen's Who Wants to Live Forever, Adel's Skyfall) - vocals are too far away. In the end I think that without the comparison they are really good headphones, but not for all. I would say that LCD-4's are like cameral, intimate concert in a small club with great acoustics. 1266 are like a concert in a big hall.
When I tried to compare them directly to LCD-4 (which is not easy because of TC specific placement on head) this is where the problem started. Bass seems to me that is on similar level, just that both headphones serve it differently. TC's soundstage is bigger, but because of that I feel that details in sounds are harder to notice (they are there but far from you). I belive that because of that, what May brings to the table is more clear on Audeze then Abyss. Also instrument placement seems similar. I've made some test with DMS Abyss tests and LCD-4 were maybe even a bit more precised. Generaly both headphones are different jet I felt that they are in the same league. But one of them is overpriced (especially now after Abyss rised the prices). If you have LCD-4 I would recomend something more like Susvara probably. Abyss will give you bigger soundstage, and a bit different take on bass. If you had Susvaras (or maybe LCD-5's?) then you could pick from both of them. Maybe I would give a little node to TC (because of different presentation in midrange).
As I said I'll be still evaluating the TC's. They are one of a kind, that's for sure. For good and for bad. I have some thoughts about the company that may damage my jugement too.
