I've sold the Eikons and still have the 600s. I found the Eikons to be just lacking in overall resolution and detail for their pricetag, and were a little wonky through the lower treble. The mids/treble on the 600s is right in the 'Goldilocks' zone for me.
That’s great to hear! Yeah I’ve had several ZMFs they’re more about tonality than technicality but surprising the 600s can compete at their price point. No idea they were so airy. With the right amp that could fill their bottom end that sounds like a great deal.

Leather pads for bass, velour for treble right?
Usually. I've never enjoyed pad-rolling with the HD6X0 series, it always compromises their already excellently engineered sound.

Yes, agree completely. Stock pads are best for sound. Why mess with long proven perfection?

Burson Composer -> darkvoice (Tungsol 5998 + VT231) -> HD600 Marble + dekoni fenestrated sheepskin

Sounds awesome!
Good choice with the Dekoni Fenestrated Sheepskin (and the TS 5998…). From my study/office at home:

After the above, which is excellent, the Sennheiser HD600 (Custom Cans UK mod) have never sounded more musically realistic:

This headphone continually knocks my socks off. Currently running it with a Forza Noir MkII cable from the Singxer SA-1 fed by the SMSL SU-9 dac/xDuoo x10T II (transport) combo. Best i’ve heard, and I’ve owned quite a few newer/more expensive headphones

Two possible next stops for you and HD-600:
1. Custom Cans UK driver backweight modification: $70 approximate.
2. Schiit Audio Valhalla II output transformer less tube hpa: $349 + shipping. The Valhalla II can handle high and low impedance hps. I own it, with three other tube hpa, and use it with Beyerdynamic DT880 at 600 ohms to Audeze LCD-X at 20 ohms.

Do you know if there a US source for the custom cans mod or do you order it direct from them in the uk?
Thanks.

I don't know about the mod dude. I tend to be of the mind that you can only worsen the sound by changing what Senn intended. But I'm open to your impressions regarding what Custon Cans UK did to change the sound characteristics of your 600.

Re amps was looking to get a custom built Bottlehead Crack. Prob will go that route soon.

Totally agree with you about not doing the mod.

No harm in the mods if they are reversible. I love the curtain mod on the 58X. Transforms it into a much better headphone. I need to read up on the Custom Cans mods. Don't really know anything about them.

The Custom Cans UK mod is reversible. I have comments on it and on a modification by me: post #20,986 of this thread. Two photographs from that post are below. [I see that you ‘liked’ that post.]

Direct. You can contact @jfunk, a fellow HeadFier and principal of Custom Cans, for more information.
