Here are my impressions of the T+A equipment.
As posted earlier, I was primarily interested in a server/streamer upgrade, but also listened to the HA200, P and P-SE while I had the chance to do so at the dealer.
I also tried the Mola Mola Tambaqui DAC/amp as it was also available.
Everything below is just an impression - not a conclusive judgement on what is ultimately best.
I'm a single-headphone kinda guy, so the P or P-SE would have to be overall better than my existing HEKse's for all music types.
In Round 1 at the dealer, all I needed to decide was which component I should take back with me for a home trial.
I was already taking the Grimm MU1 server (see the Grimm thread over at AS forum) and just needed to know if...
(a) Would the P or P-SE overall sound better than my HEKse? And if so....
(b) Would the HA200 have better synergy than my existing DAVE for driving the P or P-SE? And...
(c) Would the HA200 have better synergy than DAVE for interfacing with the MU1?
As
@DarginMahkum had noted, both P and P-SE seemed faster than my HEK in the lower-mids and upper bass. And both were darker (the P more so) and both less efficient (needed around 3-4dB more on the volume control). But the HEK was more comfortable. In this short comparison, I found it hard to justify the extra cost of the P over the P-SE, even though it did some things really well. And I didn't appreciate it's extra weight, so I chose the P-SE to take back home.
Moving onto the DAC/Amps, I really liked the HA200 and found its versatile controls, e.g. tone controls, useful and effective. However, it gave no obvious additional SQ synergy over DAVE with either the headphones or with MU1.
Following on from the HA200, the (more expensive) Mola Mola won on detail and clarity, but unexpectedly showed up some sibilance on the P-SE on a familiar female vocal that I had never noticed before. In short, both the new DAC/Amps gave a good first impression, but neither gave me a compelling reason to change from my DAVE.
In conclusion, I took back the MU1 and P-SE for a home trial. Round 2 to immediately follow.
