I find it hard to accept level criticism of the TT2 sounding in any way that's it's been negatively described. (Words like ruthless or bleached are either a mistake, trash talk, or potential trolling.) The TT2 is a natural sounding as any Chord DAC, and more accurate than most.
I can relate to first impressions of the TT2 being a lot to take in. However it was no different for me going from:
Meridian Explorer to Chord Mojo
Mojo to Hugo 2
Hugo 2 to TT2.
When I got the Mojo is took almost two weeks before I realised the Mojo was right. Then many more weeks before I stopped longing for the thicker less detailed bloom of the Meridian Explorer. Similarly when I got the Hugo 2 there was so much detail, I could not see or hear straight. That was with music I knew on the Mojo. What I did was straight away focus on the tonal balance, and tonal warmth. I quickly decided tonal balance was perfect, and warmth was only a natural level or warmth. Just a case of sitting with it for month of solid music, which I did to adjust. Given what reviewers were saying about the Hugo 2, I knew I had no problems with it. Then it took me best part of a month to fully adjust to Hugo 2.
Then TT2. With music I knew, again I was outfaced. However with music that I didn't know, like I had two new unopened CDs, the TT2 was astonishing. I could barely take it in. It was so together, and so outright prefect. Over time I adjusted to the TT2 with music I already knew. Now six months later and for a long time, I am so relaxed with the TT2 that I don't even think about it.
Initially though with the TT2, I would sometimes find myself questioning some sounds. (I was like 'what?'.) However I knew the DAC was right. It was then a case of telling myself that was how that sound was supposed to sound. (Now months down the line, I was right.) However it doesn't detract from the fact that the TT2 was initially at times a lot to take in. That is only to be expected though. It is an extremely high end piece of audio equipment. It's going to sound unusual at times, if the listener is not used to that level of resolution and resolving power. It's going to make sounds, sound like we never heard them before, in ways we'd never thought.
(It reminds me of when I first got the Hugo 2. Not always but there were moments when it scared me with what it could do. I remember also clearly reading someone mentioned that the Hugo 2 was 'scarily good'.)
One of the other steps in the experience is what cabling and electronics you are using. Never underestimate analogue cabling. Having bright cabling is not going to do any favours. I never buy cables unless I can see reviews. Like I won't just go on the AudioQuest website and think, that one costs more so it must be better. Sticking to neutral partnering kit is paramount. If you don't and criticise, then who cares. Honestly, if you are struggling with the TT2 at first give it time. If you are still struggling months later look at your cabling, electronics, and headphones.
E.g. I recently changed a slightly bright cable for a neutral one. The result was that the soundstage that was a little forward, improved a noticeably comfortable amount. The overall quality of the cable was better too, and the sound was more civilised while more revealing. By civilised I don't mean boring or flat, I mean 'oh …. right'. (TT2 still instantly takes my head clean off if I give it some AC/DC.)
