Back to matching an amp with the HD-600. It's not just the wpc at 300 ohms, it's how it deals with dynamics and sound stage.

My Ragnarok 1 which is a beast has 3x the wpc at 300 ohms than the OTL amp: Bottlehead Crack. My crack is much more musical, even suave then the Rag (600 only). Yes the BHC has more THD. But the Rag/600 doesn't have the sound stage, dynamics, or such a pleasant treble. My Rag drives all my other cans, and is good enough to drive a Susvara or a Raal - or a Maggie .7i.
I have a similar experience using any of the phones from the 600 family with the Valhalla and the Lyr 2. I prefer all of the 600 family of phones using the OTL tube Valhalla over the tube hybrid Lyr (even though they still sound good on the Lyr). The soundstage really expands using the Valhalla. Conversely the Lyr excels at powering the planar phones I use (Aeon Flow X, Sundara, Modhouse Argon Mk 2, Deva, etc.).

I ordered new pads from a norwegian online store (Evenstad musikk) and got pads and foam in the bag. It looked like it came straight from Sennheiser. I would think that foam is included when you buy new stock Sennheiser pads.

And that brings me to the problem: new pads.
I bought a pair of 2012-ish well worn HD600 which reaked of smoke, really, really bad. I did a quick test just to make shure they worked before I tore them apart for cleaning. And my god, did they sound good. I had the 6XX before and did not like them at all. I found them very veiled and kind of compressed with little separation.

But the pads where really worn and the seam where loose so they had to go. I put everything else, except the drivers in soap and water and soaked them 24 hours before scrubbing everything clean. I, of course, managed to break a driver when removing dust (on of those extremely thin wires). So I bought a new driver and pads (new type) for them. The new and old driver had an imbalance. The new one was louder across the board, that got better after some hours of burn in.

But, with the new pads, they did not sound like they did with the old worn out pads. It sounded much better with the old pads, so I really hope they will sound like that again, after the new pads are worn and compressed and I really hope that its not the new driver that is to blame for the sound changes.

For reference I use the HD600`s with a TDA1387 NOS DAC - Asgard 1 & 2 and Bottlehead S.E.X.

Which TDA1387 NOS DAC?

USB-powered? With 2x 4x TDA1387 in parallel? Must draw a bit of power!

Looks like a very simple circuit, the paralleled output of the DAC chips goes straight to the line out via a coupling capacitor. That is where an upgrade can make a big difference…

The only problem is: decent coupling caps are big and won’t fit inside the case (and will cost more than the DAC)😀.

I fitted some Obbligatos on the output of my TeraDak Chameleon (16x TDA1543 in two banks of 8).

Sometimes it happens when the DAC loses synch with the source. Does it mute?

Hey guys,

I wanted to see if any of you guys have heard the Eikon and the HD600 and could do a comparison for me? I’m curious if the 600s have similar highs as the Eikon. Without a tube amp the Eikons high can be a little harsh but I feel like they might be more detailed. Obviously totally difference price points but I’m thinking of picking up the 600s for a second pair and getting rid of my Eikons. I know I wouldn’t get that amazing subbass but I feel like I would get a more smoother, even mid range like the 650s while hopefully not losing out on too many of the highs. Any thoughts?

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.

Great input. Let me add another point.

I can't remember much about Eikon. It was too long ago, and it wasn't mine. But I had the Auteur for a quite some time. The ZMFs felt closed in, and HD600 feels more open and airier. No, you're not losing out much in the highs. Actually I still prefer HD600. Less colored. Similar details.

Try the HD600 with Massdrop Velour pads.
