Reading between the lines on Aornic's review a bit... it seems like the 660S has quite a bit in common with the Elear. Can anyone who's heard both weigh in on that?
Deoxit does a decent job, but for me the best contact cleaner is a simple 50/50 mixture of Naval Jelly and water. I leave it on for one minute and then rinse with a Q-tip dipped in distilled water. If the goal is to remove oxidation, the phosphoric acid in Naval Jelly will do exactly that, with no additional residue.I've noticed that with tubes using Deoxit helps with some that have a hum or slight channel imbalances and many times the older NOS tubes have some corrosion on the pins so I usually use the Deoxit cleaner (red color) and let it sit for a day, wipe it off and use the preserver (yellow/gold color). Most times I don't see any oxidization but the way I look at it the price of Deoxit is so cheap since a 7.4ml bottle that I got in 2014 doesn't even look like I used any and yes its easy to hear a difference if there was even a little issue with the quality of the electrical connection.
To cut a long story short the HD600 wins again. Seems to be a increasingly common consensus for those that have heard all three.
The reason why Sennheiser will keep making it, hopefull,y whilst discontinuing the 650. I'll stick with mine THANKS....Over and out!
After owning both the HD650 and HD600, HD600 got sold and was easily replaced by a custom Ypsilon driver build that ended up also replacing the HD650, but I still have my HD650 since it was one of the first "better" headphones I got. I'm a little disappointed with most of the reviews since I was hoping the HD660S would take on more of the characteristics of the HD700 which I like better than the HD600 and HD650 but I'll be modding my HD6XX when it gets here so. One thing I like about the HD660S is the new look over the HD600 which looks like cheap imitation marble to the slightly drab HD650 grey.Well thanks for the tips everyone, maybe I'll give the Deoxit a shot, my tubes can use some cleaning as well. Considering another DIY cable, this time with some bulk cable from either Cardas or Moon Audio. Going to reach out to Senn as well, see if they will part with one of those HD6XX cables for a reasonable price.
All this talk of the 600 besting the 660S has got me curious. Never owned the 600, went right to the 650. I live in an audio store wasteland, but thinking I'm going to get my hands on a pair somehow for a side-by-side with the 660S, winner takes all (of my head-space )

Finally someone that cuts off the BS terms and simply says "this headphone has more/less bass or impact than the other...".
Made an interesting discovery today...
I had previously made a custom cable for my HD650s (5 ft long, 26 AWG OCC coper, Oyaide rhodium-plated connectors) and I was using it with my HD660S given that the 9 ft cable is so unwieldy. I noticed there was a significant difference in sound quality between my cable and the stock Sennheiser cable. Now, I am not one to argue that cables make a huge difference in sound quality, I've thought quite the opposite in the past, but this was a HUGE difference in soundstage, detail, and clarity. I thought, well since my cable is 26 AWG, maybe the HD660S is very sensitive to changes in cable resistance. So, I made a makeshift cable with some 24 AWG OCC wire I had lying around. While the 24 AWG cable was an improvement, the stock Sennheiser cable was still clearly better. I can't imagine that Sennheiser uses larger than 24 AWG wire for the cable, that is plenty for any headphone, so there is some other Deutsche trickery at work here...
TBH I am shocked, like I said, never was one to argue that cables significantly alter sound quality, but the difference here is undeniable. Unfortunately, this means I am stuck with a 9 ft cable until I can find something that sounds as good lol
I just found one thing confusing.... He days the hd660 as more bass body and impacto than the other but at the same time sounds leaner.... That seems weird....
Is the amp that the reviewer uses a tube amp?
