Will do. How do you think of them compared to the HD 600? 

They are brighter and thinner sounding than the 600s to me. I still really enjoy them though. The Lyr 2 will drive them very well.

Which version of the Sextett do you have? I don't mind thinner and brighter than the HD 600. That's good to hear.

I know the radiators are white, so I'm guessing late production.  I purchased them new in either 1978 or 1979.  I can't remember for sure because it was a long time ago.  Just put new oe pads on them last fall.

You've had them long than I've been on this earth. I'll have to wait and see what mine are, couldn't really see the radiators in the pictures, I'm assuming Orange is mid production and white is late production give the headband is solid without holes.

Solid headband on mine.

 Ah, there must only be like a couple years between the different production versions as they came out in 1975 I believe.

I just got the K240 Sextett, seems to be a late production. It is in pretty good condition, can tell it needs some work though, but I already have two new sets of K240 pads from my MKII. It sounds best with the K240/271 velour pads and driver foam cover, got rid of the weird hollowness and thinness I got with the pleather pads. The foam inside the earcups is deteriorating and it has lost it's elasticity in the headband, but I'll fix that a different time. Has more bass than I expected from a 35 year old headphone and it does sound better than the K240 MKII I had, no nasty treble spike and sounds clearer and less colored. Need to spend some time with it. More refined and detailed than I was expecting. It's also a beast to drive, it's the first headphone I had to use high gain on my amp to get going.

Settle in with them for a while. I find them a fun change up to listen to. On my flashback Sundays I like to use them.

True, they are interesting sounding, did some pad swapping to get them to sound a bit better as well as better comfort. In some ways they are better than my other headphones but they are also not better in other ways. Quite an unique sound.

The Lyr should have enough juice to get the AKG K240 Sextett to work, has anyone else tried to send more power into them? 

post #1061 of 1065

I'm thinking these more voltage gain than current gain. I've used them with two different Cavalli based DIY amps with great results - the Compact Tube Hybrid -- has no issues what so ever because it has a lot of voltage gain depending on the tube used. The CTH voltage swing is 12v. The EHHA Rev A has 30v rails so it has tons of voltage swing to get them going. I'm using a gain of 5 I believe. I've been swapping back and forth between my MPs and the K7XXs and I still think the Sextetts edge them out.

Really interesting I'm thing of buying a used Liquid Fire for HD800 and LCD3F pairing but the AKG Sextetts well my guess is they need that sort of juice!

The Liquid Fire is a kissing cousin to the EHHA. They both are DC coupled, embedded hybrids. The tubes aren't in a separate voltage gain stage, but are a part of the circuit like a capacitor would be. The LF is more powerful though and stays in Class A for longer and uses different tubes -- E88CC vs. ECC86. Cavalli makes some great gear both commercial and DIY. I wish he'd do another DIY amp, but I'm not counting on it.

Are you not counting Glass and Gold etc..?

I was just comparing LF to EHHA. Liquid Crimson would be similar to those two, but only uses one E88CC tube instead of two. LG is a more traditional hybrid and LG is solid state I believe, so I didn't compare them.
