Secondhand…Anyone have a preference because along with the HD700’s (obviously quite different animals) are headphones i’m looking to acquire at the right price.
I personally would go with the th900 if you don’t care about leakage or isolation. If you plan for portable usage, the dt177x go might be a better option.

No portable usage but it would be nice to keep things a bit quieter at home for the missus sometimes, and I liked my old DT770’s 250’s so just looking out for something along those lines but with a better detail, separation but still have that bass/sub bass going on.

The th900 doesn’t leak that much, so at normal listening levels I don’t think that would be an issue then. The th900 sub bass is truely near that end game level. The 1770 is just a muddy bassy (not really even subbass) mess imo when you compare it to the th900 or the dt1990. I would say that the 770 250 ohm has the potential to have better subbass then the 1770. The fostex biodynamic drivers are made for subbass, and I still think that the th900 or other biodynamic variants are the best for it.
I currently own a th900mk2 driver converted purple heart, and it really is amazing for subbass in most ways. The th900 separation is also very interesting sounding, and the 900 also has more detail then the 1770 imo. The only thing the dt1770 has over the 900 imo is physical sound width and build quality. But I personally still would take the 900

I don’t own any of these, but my friend does have th900mk2. It’s gorgeous. I’ve tried it for a few hours. It’s very comfort, and it sounds incredible exciting too. If you have budget, i don’t think you will be disappointed on th900. (One thing i’d like to point out, it seems th900 is quite picky on amps…)

skip the 1770 and get the TH900, Dt 177xGo or Cascades
I own the DT 770 and the 1990s
I wanted the 1770 to be an upgrade over the 770s - tried it a few times, but was not good at all
The 1770s have a one-sound low end, muddy - not acceptable for the money. Highs are also not perfectly controlled… speed and timbre are good
so in April I jumped on the Massdrop DT 177x Go Drop, because of better soundtuning, balanced…
but got a good deal a few weeks ago on the Focal Elegia and cancelled the 177x Go preorder.
I could not be happier, but will have a look on the Cascades next year.
Maybe you also take the Campfire Audio Cascade into consideration? better Isolation than the TH900
from what I read
TH900 and Cascades are both fun - designwise the Cascades are my cup of tee

If you want portable, the Cascades are great and well, but personally I don’t think they’re on the same level as the th900

have here in munich no dealer for the TH900 - if I get a chance to listen anytime - I will.
IEM’s aren’t really my thing and I don’t need them to be portable…One more closed back I’ve thought about is the Ultrasone Signature Pro, anyone have an opinion on these?
What iems are you talking about?
The ultrasone headphones are something you kinda have to go and hear, as they can be really strange sometimes. Personally I didn’t enjoy it that much, as the presentation was strange, but the build and comfort were great, and the isolation was really good, but imo it’s not as enjoyable of a headphone compared to what’s been mentioned here. It almost sounds artificial and exaggerated. I would say it’s more for studio monitoring or mixing then musical enjoyment
Also perhaps check out the Denon d7200 or d9200. Also biodynamic and sound really good

Cheers guys I appreciate your input 
MON I have looked into the Denon option too thanks 
I think it’s just a matter of picking one of the above discussed headphones and wait for one to come up at a good price, as it stands I think Fostex is the way to go but the TH900 might be a bit too step💰wise but we’ll see, otherwise maybe the Purplehearts or the TH-X00?
The purplehearts are the most fun (v shaped) out of the batch, and the ebony are the most balanced. All of them have the great properties of the biodynamic, but just different frequency responses

I take it most of the TH range take well to tubes as well?
I should say though that the soundstage on the th900 is better and more defined. The tr-x00’s are pretty narrow and intimate sounding.
They take ok to tubes, but because they are low impedance, you may have mixed results

You’d like to think so considering it’s price point lol.
Well it’s just made to be a bit less intimate and in your face then the x00 line. That’s just an added benefit
tried a few Ultrasone - the signature pro is no fun headphone - more a boring monitoring can like the Sony 7506 with better extension/resolution - the marketed soundstage is not as wide as expected …
Ultrasone sits 30km away from my place. Met the people at munich high end and wanted to visit the store
not yet sure about the Adam Audio SP-5 - but no… you want fun

Would you agree with this comparison? if so do the Purplehearts fall between these two when it comes to the overall sound etc?..thanks again buddy 
I would say that the bass on the purplehearts is more prevalent and slightly better then the regular tr-x00, but still not as good as the th900 imo. So yes it does fall in the middle. But the treble is also boosted as well, so it can be a bit more fatiguing compared to the other tr-x00

If you’re into a more neutral sound you could try the TH610. I used to have both those and the TH900. Admittedly the 900 is a more “fun” sounding set, but for pure sound quality the 610 isn’t that far behind.
