Don't take it that I was trying to shoot you down - OK
Whne the comment was made about the HD600 I had to step in. People will be making buying decisions based on what is said - and being a long time owner of the HD600, and having the Sabre with me now, I just want to make sure people are aware of what is real, and what is simply excitement about a new product.
Whilst I have the Sabre (and I'm pretty sure this is the final tuned model), I only have the one filter - so everything I say will be based on that. Bob, Vince and I have talked at length regarding the ideal tonality changes for the filter systems, and we've given our guidance for what would give the most "value" and cover most bases. I'm confident that Bob will deliver on the filters - he knows what is required, and he is very good at delivering based on what we advise (as long as it fits into his own ideas on sonic signature - he is after all the genius behind the tuning - all we are is the critiquers on the side). Personally I thought the filters on the Atlas were too close (not enough variety). This is something I think will be fixed with Sabre and Master.
I also have the Delta V2 (I bought a pair). Currently waiting for a replacement as it looks like the bass driver on side is blown or at least crippled - it's OK - this sort of thing can happen - no reflection on Bob ior his QC or anything. So I can't compare the new Delta - but I will try and show later (if I get time) the effect of filters on the good driver.
Going to take me a few hours to put all this together. I'd better get started!
