Yeah...Ian's design philosophy is you should get out what you put in. Nothing more and nothing less. I guess that results in this "transparent" bass that you are witnessing.
Andrew and Ian are doing some amazing things. I am glad to see that he finally has some good engineering talent. It was severely lacking in the past. A lot has been cleaned up and I do think that Ian can go to his grave (not anytime soon) knowing that he created something very unique in the industry on many fronts.
