I am loving it, before when I owned Hugo 2 and Diana V2, I was lusting after better. I went into both TT2 and AB-1266 blindly and was not disappointed. To me, M Scaler is not worth the 4k asking price. Can I hear a difference, yes. But, it just does not feel right spending 5k on AB-1266, 5k on TT2 and how much you get for that money, then M Scaler for 4k just feels like a final tweak for someone who is either more dedicated to the hobby, or has more money to spend.How are you finding the 1266 with TT2??
I'm tempted to either get TT2 + Mscaler with mine, or add the Formula S + powerman to my RME ADI2, neither seem cheap to do
As far as getting Formula S+P, you hear a lot of good things about it. However, if you already have TT2, I don't think it makes that much sense. Will it alter the sound? I am sure it will, and maybe you will like it more, but I don't think it is necessary, especially if you drive AB-1266 from TT2's rear XLRs.
Obviously I am biased towards what I own, but I am also very critical of things I purchased in the past and did not like, so I hope you find my message honest. If you ask me, I would get TT2 with 1266, as it is the most cost effective setup, I found so far.
