What are you amping the K701 with? - Page 3

Sorry I haven’t checked this thread in a while.

When new the 701’s come across as almost as sharp sounding (bright) as my MDR SA5000’s, Very similar to the 880’s. Even when new the midrange was glorious, the bass was tight and well controlled but lacked ultimate extension and power.

Then over the next 100 hours or so there was a gradual change. They no longer struck me as being bright at all. As far as high frequency energy I believe that they settled almost exactly between the 880’s and the 650’s. Please don’t think that because I view them to be warmer than the 880’s or my 5000’s that they lack resolution. The 701’s reveal more inner detail than my 5000’s, but they do so with less HF sheen or distortion. The midrange is both lush and tremendously transparent. Midrange is still AKG’s strong suit. The bottom end fleshed out nicely. It still lags behind the 650’s in sheer quantity of bass but it has good extension and good power with great speed and definition.

I believe that the 701’s once broken in are the best all around headphone in current production. They do everything at least very well. They are extremely even-handed, so even handed that I believe exceptional results can be had with any quality amplifier. Like any of the true contenders they cry out for quality amplification and sources, but unlike some they won’t sound terrible if driven from a modest amp.

I predict cold, cool, bright. In great synergy with its looks.

I have about 30 hours on them now and they really aren't so bright what they used to be out of the box. They sure aren't as bright as SA5k or DT880. However what I've spotted most clearly is that the edginess which they had first is gone. They even fatigued me at first but now the sound has smoothed out nicely.

These sure are nice all around headphones but I'd say that SA5k is even better. SA5k handles rock much better and goes well with other music also. With rock music K701 still doesn't quite do it for me. There's just not enough energy and speed in there. K701 still does it MUCH better than 650s which I have now found out to be very bad for rock.

Not all "rock" is equal. I find the HD650 perfect for Mark Lanegan, Jeff Buckley, Lou Reed, Lucinda Williams, XTC, Steve Earle, EELS, ...

So, do you guys think that either a Gilmore Lite or a Headroom Micro can provide enough juice to drive the K701s adequately?

Well yes you're right. Actually it's hard rock and metal which doesn't fit 650s. Pink Floyd sounds nice with 650s.

Simple... the go-vibe has a lot of drive for a 9v powered amp, with the right opamp installed. Who ever made a rule that you have to go big $$ and complexity for a good amp?

Could also be that the K501 is a bit weak in bass... seems like all the supposedly "hard to drive" cans are somewhat lacking in bass punch, and people are looking for a greater amount of it.

Yep very true.



And even my Zero amplifier, using an AD823 at unity gain like a buffer (driven by a OPA2227), and powered with 12V, seemingly has an endless "juice" with all my phones, low or high impedance. And dynamics are never lacking at all... (PS: after my finding, fewtch, I'd suggest you to try an AD823, too, in the Go-Vibe)

If I can get my hands on one, I'll do that... pretty happy with the AD8620, but it never hurts to try a different sound.

I am not sure about the Gilmore Lite, but I would say you need a little more power than the Micro, to make these cans do their job.

I can give an answer from real experience, sometime next week.

As the K701 sounds very good with GS-1, I'd say Gilmore Lite with Dedicated PSU is definitely more than adequate to driver K701.

Which gain position (high or low) on GS-1 with your K701?

Hello

Im planning to buy either HD650 or K 701. I listen to every type of music, from classical to pop to metal even.

Im also planning to buy a good amp to these. But i can not buy both headphones and amp at the same time due to my limited budget. My source is a Hercules Fortissimo II soundcard with a headphone output (fairly good Cirrus Logic chips). Will it be able to drive either of these headphones until i can buy a amp (I mean, drive it "ok/good", but not "excellent")?

Based on this info, what headphone do you guys recommend?

Right now im using Philips HD890 and my soundcard has no problem driving them.

You really should listen to them yourself before deciding.

But if you're looking a better all arounder which would perform well in every music genre then it'd definitely be K701.

Always set to low as it's more than enough to my ears. 9 is the loudest I can handle to listen with on long listening session.
