Yes, after owning Senn HD650's and a pair of HD6xx, I was happy to move them on fairly quickly, the HD540's just gave, and give, me so much more, even though they have a little less midrange fine detail. They make me joyful to listen with, the 650's just didn't have that. I am looking forward to...

Ok, thanks for clarifying that. From what I've heard about the HD660's, especially the new HD660S, I think I'd like them and will look at hearing a pair once I get more settled in my new home. I'm going to leave both of my HD540s as they are for the time being, I can enjoy them as slightly...

And thank you for the pictures. Very interesting to see the white felt rings and I can see that the foams behind the pads seems to be really packed into every part of the driver frame, as in the 2nd jpg ending in '912', mine were never that packed in. Maybe the white felts add pressure on the...

Blimey, from what I hear the HD660s are not dull headphones, so if your HD540s are brighter than they are that is not normal ...... unless you are still using the stock cable that came with them! That combination WILL give you exposed, forward and grainy upper mids and top end, I had many years...

This is the state of the outer foams of my No 2 HD540s, no wonder they sound brighter and thinner of tone in the upper mids and treble! They are obviously the original foams and the burnt orange foamy part is falling apart, needing to be gently brushed out of the back of the driver. What is...

Well, I'd love to have another tube amp or preamp again. My experience with the HD540s has always been a better one with tubes/valves somewhere, usually the preamp. After selling my fabulous Elekit TU8500 preamp around 18 months ago, I now really miss the brilliance of running my DACs into it...

HD540 Ref1s No 1 v HD540 Refs No2: After so many years now with the utter smoothness of the No 1s, even just a smidge dark compared to many new cans, and the relatively 'bright' No 2s, I have at last pulled apart the No 1s just to see if I had done what I was now suspecting, blocked some of the...

No 2 HD540 Refs have received their new wang pleather pads now, plus one of the thin foams each side, 3mm, same as for the No1 HD540s. There has always been something a little different about these No 2 540s, they are the same impedance at 600 ohms and even using the same Mogami cable, foams and...

Hi IgorUA, I buy from this seller, it may be the same as you've tried before. https://www.ebay.com.au/itm/261338110308?var=560432574135 I now only buy the pleather pads with the oval ear openings and ONLY the 3mm foams, which I ask for and which he sent me a few days ago. Often he will send a...

Ah, many of us long for those delicious original pads, so soft that they could be worn for hours and I did often! Until the second set died some years back and by then they were unobtainable. The second pair of HD540 Refs I bought a couple of years ago came with the same looking pads in your...

I have a new addition to the electronics family, an April Music Stello HP100 h/phone amp/preamp, bought second hand ... well, naturally, since the amp came out in 2006, making it as 'old' as the FrankenZero, but at a $595US price at the time. Beautifully built, it was introduced as an intro to...

A history lesson - for me: Most of my Head-fi listening (in recent months) has been with using my 15 year old and heavily updated Tianyun Zero DAC (FrankenZero or just Frankie) with the Burson Vivid V6 output module into the Schiit Magni 3+, a very good combo, full of transparent detail and...

In light of Lantian's reply, maybe sending them off to Sennheiser is in order, as I imagine the drivers in the HD540 Golds are a matched pair and just buying a single unit on-line may not turn out to be a good idea. Maybe Sennheiser can service the complete HD540 Gold for you.
