    All carbons now shipped with silver grills, csrbon+gold discontinued due to low demand.

    @Garuspik

    which impedance adaptor would you reccomend, 75, 150, or 200 ohm. I'm looking to pick one up for my Verums. Thank you

    Is lower better since it can deliver more current into the headphones? I =V/R, so if your amp specs are available you might be able to optimize the max power your amp can put into your headphones, I believe just add 8 ohms to the adapter value? Phase wouldn't matter cause the resistor is before the headphone and a resistors value doesn't change with frequency but please correct me if I'm wrong.

    There are some upgrades on the Verum 1 no one is talking about: 3,5 mm connectors instead of 2,5 mm and some changing in the fixation of the drivers

    Verum 2 is totally new headphone, with another principle. I have several assembled cups now, but no single finished unit. When I'll have finished units I'll make presentation to SBAF, explain all the technology that stands behind it and answer all questions except "how do they sound?" :D

    What I'll be ready to present at the beginning of next year is new headband for Verum 1:

    NOTE! Leather strap is not finished yet on photo. It's still in test stage. New headband is significantly more compact, comfrotable, lightweight and good looking. As I've promised before - it'll be available as an upgrade kit to any Verum 1 owner at self cost.
    I guess that a set of steel headband, leather strap, all knobs + international shipping will cost about 40$.
    That's not an advertesing, that's a my way of telling "thank you for your support".
    Headband is easily intherchangable.

    About time schedule - all earpads ordered till 10 of December are already shipped. All headphones ordered till 1st December are also shipped. I still have delays, but they're significantly reduced. Also I'm happy that none of units produced during at least 3 last month caused problems. That's the fact I'm happy about the most :D

    p.s. Only today I've finally received a headband I'm happy with. So no, they're not ready for mass production yet.

    Nice! I noticed on another forum that there may have been a production change to switch to an on-ear style of ear pad instead of the original over-ear. Can you please confirm whether that impacts this batch and whether the original style pad is still available?

    One guy on Head-fi literally terrorized me about pads, knobs etc. No changes were made - it's over ear pads. Anyway I do suggest leather pads sound&comfort wise.

    That headband looks sexy! You made my day when you said you shipped all orders made till December 1st, I ordered at November 25th, so can't wait to get my pair! :D

    Side note: the repaired Verum 1 arrived December 24th - great xmas gift, Garuspik :)

    In their absence, the ZMF Auteur arrived and I could listen to those for days straight nearly, so I was apprehensive about how I'd rate the Verums now. Then I discovered something else - and I wonder if anyone else noticed this:

    The Verums just excel (in dynamics) with my (fully) balanced push pull tube amp.. while my HD600 and Auteur sound best on my single ended amp. Especially the Auteur seems literally made for SET, so much synergy and suffers no SET sluggishness that I generally experience.

    For background, I'm using Tidal Hifi > RME (optical over USB) > amps. Both my SET and Balanced tube amp are extremely simple and deliberatelly have single stage amplification (2xE280F resp. 4xE180F) plus use an identical tube-regulated power supply and very similar Lundahl output transformer (LL2766 with 6 and 60 Ohm outputs, both using all windings). So they're very comparable although arguably the size of the transformer is low for SET and a slight low roll-off is there.

    Back to the Verum, it's dynamics really shine with P/P - it's the only combo that to me yields the 'being there' factor .. with enough attack and detail in the attack that makes me forget I'm listening to a transducer. It's especially apparent in lively tracks.. whereas the music is more mellow, the Auteur starts to shine..and when I'm just listening to violins and piano, well my well aged HD600's comes into play like nothing else - they can express a brilliant classical artist like nothing else I've heard just yet (and that's limited compared to some of you).

    Another boggling aspect is attack vs impact/heft/sustain... because despite the Verum's quality and bass extension, kick drums have more impact on the Auteur but yet the Verum can play the Dave Brubeck Quartet's Bossa Nova USA with an authority that the Auteur just can't and I'm not entirely sure what's what there (any care to comment what's going on?).

    Anyway I'm supremely happy with any of my 3 headphones now, all of which have their domain (and amp)... I've got no use for my Violectric V220 though; it's getting trounced by my diy tube amps which I'm still improving. But I was surprised on the synergies with the amp's methodology and I haven't seen any comments on SBAF other that generally SET generally seems to rule the roast..

    I've had a pretty long search of the appropriate threads but does anyone have impressions of the headphone on an Asgard 3?

    The only mention of this pairing that I've found is in Currawong's review of the Asgard 3:

    I don't put much stock in Currawong unfortunately. Tossing up between this and the SW51 for Verums.

    The output impedance of the SW51 is too high for the Verums.
    What gear are you currently running them out of?

    Output impedance matters for dynamic drivers. For those transducers that don't have inductance it's usually doesn't mean anything.
    However often higher impedance amps can't deliver 100-200 mW of clean power at 8 ohm that Verum 1 require.

    Indeed, the amp will likely be severely distorting with the Verums.

    No SW51+ with the Verum unless you like extreme distortion and clipping. V=IR.
