https://ultrasone.sumupstore.com/produkt/founders-series-offene-bauweise There are now open edition for the founder series, unfortunately not much information about it and no review of the founders series i can find.

From what ive experienced on ultrasone, they always have a 6khz peak so i would EQing down there, the rest of the frequencies are fine for me.

Thanks for the impression, the thing is currently i dont have a high end amp to drive the TC, at my current state i can only get portable/transportable option. So is tc still the right option?

Hello, anyone here have both the Diana MR and TC? The used TC price already close to brand new MR right now and i wonder is the TC an overall better headphone than MR or they just complement each other?

Depends on your budjet, some of the good dongles that match well with my ultrasone are Lootoo paw S1/2, Cayin Ru/6/7, L&P W2/4.

Fortunately i get my id1 for about us60 with the earpad included , because the seller which is my friend thoughts its broken or something because of low volume output, though he regret selling it after i plug them in a real headphone amp. :floatsmile: The earpad is actually a DCA Alpha pads that...

Yes, mine has the black sticker but as you said i am not sure it really attributed to the sound. I am using a modified gainclone Lm1875 to drive them (20 watt per channel) so i dont have trouble driving them, drives better than a high end modern cayin amp the last time i tested them. Anyway its...

I used to own (and heard) lot of different vintage planars, and for me this is one of (if not the best) vintage planars, so it doesnt mean that all vintage planars will sound this good.

I am very lucky to get it at this condition. My friend also have this but the housing is in bad condition, mine also sound better in comparison maybe because of the different pads.

They sound really good tbh, very good soundstage and resolution, but yes they are roll off on frequency extreme just like other vintage planars do. If i were to rate it, it is on par with hifiman sundara but the musicality attribute is unique to the veteran.

the world first planar headphone, wharfedale id1, still perfectly functional despite the ages.

I understand about that, i just hope that rs2 can do something about it because the 3.5mm LO output doesnt have high gain compared to 4.4mm out.

Hello anyone know how to operate RS2 as a balanced line out dac? Or just manualy crank the volume up? Anyway, ive been RS2 users for about a year and has been very happy with the purchased. The 3,5mm output and raw power leaves something to be desired with, but the SQ of 4.4mm and LO is...

yes, but adding damping materials to the housing give better results.

I have two, but already sold one.. this is one of them, the other one i think ive already posted a long time a go.
