So I got my TP1s in. There are a few things wrong with them, but Gary apologized and said he would fix all and get them back to me ASAP. I'll give him a chance to correct things and just focus on the sound right now.
I have a Metrum Octave -> Maxxed (earlier 2k9 version, all blackgates) WA6SE. I've played around with various tubes, and oddly enough I like the same setup I've been using with my Edition 8s. It must be a general personal preference thing.
One of the things wrong with the order was the pad choice... I had originally specified LCD-2 pads, but saw how big they looked in some post, so changed my order to O2s before paying. But I received LCD-2 pads, and indeed they are quite massive in person. The on-head experience is good though. I think I'll keep these and ask for a refund, esp. as I've seen some issues with the O2s wearing out prematurely.
The first day I used them I wasn't quite sure how I felt about them compared to my Edition 8s. The Ed8s certainly sounded more 'fun', but these sound more neutral, spacious, better separation. One thing was a distinct lack of low end which surprised me, esp. with the LCD-2 pads which I assumed isolated well. I even pushed them down to make sure they were sealing alright and the bass was just really recessed - and esp. it was like a stat in that it's heard but not 'felt'.
This morning I took a look at the pads and tried all sorts of adjustments. Basically I stuck the phones on my head and traced with my fingers how they were mating up, and it seemed like they needed to be twisted back quite a bit. I did that and it helped some, but then I pushed the pads forward - like really forward, maybe almost an inch. The bass came way up, at least 5 db, almost a bit to where it's a bit bloaty. Pushing back a tiny bit just about gets things about right. It feels a bit funky as the front of the pads are almost on top of my cheekbones. I think what's going on is now there is this larger area against my face where the sound can reflect against. Also there was what I perceived to be a sibilant nature which seems to have been fixed... probably more than anything is that I can get more 'oomph' out of them at a lower volume.
The LCD-2 pads are quite comfy and seem to make these feel less heavy than they are. But I do feel the need to take a break after every 2 hours or so, whereas the Ed8s are barely percerptable . The Ed8s probably have the advantage in some areas but I'll need to go back and forth. Certainly the TP1s require more power, I find I have them at 11 o'clock for a similar volume I get from the Ed8s at approx 8.
Overall from a sonics standpoint I like these quite a bit. Really nice.
