The worlds most extreme ER4-P - Page 8

ha ha - cool, just wondering.

"...the earbuds, not my wife..." LOL

Its interesting that you mention that nc8000. I've noticed that my 25ohm Denons needed volume at higher positions then my 45ohm ESW10JPN... never did figure that one out.

x2 the difference between the 225's and ED8's is only a negligible ~2 ohm's according to headroom and the difference in my pico settings is much larger for 225's, interesting how that works.

Frankly if budget is a concern at all and you don't just have money lying around that you don't know what to do with. If you want better sound from the ER4 the first thing to try is a better amp. Once you have the perfect amp and the perfect DAC and the perfect everything you want THEN you start spending $200 on things like cables.

Changing impedance on the same phone will change the sensitivity, but the drivers themselves have a sensitivity value. You can't just look at a phone's impedance and make any conclusions about sensitivity. For that matter you cannot say anything but a general statement about drivability either. The impedance is a nominal impedance. It changes with frequency.

Since this thread has become an ETY lovefest I must add my piece.

I don't care how old they are or what complaints people make about them being single drive unit. These phones are the most versatile, most impressive IEMs I have ever used. They come from a company with a audiologist background and they are designed like precision instruments.

I started with them out of an iPod 4G, then they got moved up to line-out and Cmoy, then Supermicro I, then Supermini 3 and then the LaRocco PR-II.

If there is one amp that is special with the ER4 it is the LaRocco. Whatever anyone says about ER4 bass nobody can argue that it is not deep. It may be lacking a bit in impact, but it is always deep and VERY detailed. The PR-II has a little bass contour knob that was designed to accentuate the deepest of bass without affecting the mids. When the ER4-S is connected to this amp and the knob is turned there is no limit to what the ER4 can handle. They scale up in ways you could not have imagined. They never bottom out or crap out, they just take the extra bass signal and add impact to what is still a very detailed bass playback. You could keep connecting it to better and better playback equipment and never be disappointed with how it grows.

The detail is amazing, the bass depth and detail is unbeatable. Some may argue they sound dry, but I never could complain about it. If I want lush I'll just put on the SE530. But the ER4 once you find the right tip (for me Comply) you can never complain that you are not happy.

With all this hype for multi driver IEMs I've wondered if anyone has thought about what crossover networks do to the audio signal. When you buy a $20,000 pair of speakers you are not paying for the drivers or even construction as much as you are paying for the designer's crossover design. Many things can go wrong in crossover design and when it is perfect it is still a loss to not having a crossover. A crossover is a necessary evil in speaker audio, but for IEMs I think they are a little overkill. I know many of you love your JH13 or whatever this month's FOTM is. It used to be Sensaphonics and then it was some UK sensaphonics, then it was UE and then some Westone and now it is JH. I have no doubt whatever it is this month it is good and I'm not biased against multidriver since I love the SE530, but the point is this has stood the test of time since 1991. No other IEM can claim to hold on to relevance after so much time.

Hello Folks.
Ressurecting a very old thread! I have the ER4S and love it but now have the RSA SR71-B amp so am very interested in going the balanced route with my ety's. Firstly. Are the stock cables captive to the red and blue earpieces or are they plugged in like triple.fi10's and secondly are there any cable makers making this combo to work with my amps balanced terminal.

Thanks in advance.
