K-701 Drivers in K-500 enclosure

I'm planning to buy this.

The seller says the result is a more open sound closer to the K-1000 which he also has and I will be able to test both.

I'm going to update this post as soon as I have the experience.

Still as long I don't know more please give your opinions on better capsules (such as K-701) in other bodies.

Is it risky to buy? Should I buy it if I like the sound very much and it's not really different than a K-1000 listening to various pieces of music?

The guy also told he just got a VERY nice amp, so I can test his K-701 in a K-500 case vs K-1000.

As soon as I know more I'll post it.

ps: The guy sounded honest, modest, a family man and really helpful and dedicated so I hope it's gonna be ok.

But some opinions would be appreciated so that I have some guidelines from you Head-Fi guys!

Thx a lot!

Thank you for your answer Erik!

I will ask the guy some of things you mentioned, such as really what happened to that K-500.

Oh and I will reconsider buying it as there are some really cheap new K-701 ones for 260$ on ebay which is like the same price.

Well apart from being sceptic about the deal I don't think it's impossible the the K-701 capsules sound good in that K-500 body. I am going to give you a review very soon!

Now I have listened to various pieces of music on a Bechmak DAC1 USB

And compared a [K-1000] to a [K-701 driver in a K-500 enclosure] and a Grado SR225.

Grado was nice but for me it had too artificially strong highs and was not too comfortable.

The difference between [K-1000] and the [K-701 driver in a K-500 enclosure]:

The K-1000 had a twinge of electrostatic feeling, I mean they sounded very unprepared, while the K-701driver/500enc. had that "dynamic" taste. It's like comparing the sound of a very high quality dynamic microphone (like K-701) to a condenser mic (like K-1000), I felt the same. However the difference was very slight still I could feel it, and ofc I know that the K-1000 is dynamic too, however sounds so clear that it doesn't sound like it.

As a consequence the K-701driver/K-500enclosure had a bit of less detail than the K-1000 but still performed very well and I bought it for 215$.

I'm asking you Eric is it possible that an original K-701 sounding not so good as the old K-500 has something to do with the enclosure, namely that they wanted to give a better bass to K-701 but that somehow ate up some of the detail the K-701 drivers naturally have?

So maybe the K-701 Driver in a K-500 enclosure is a nice combo resulting in a K-800? :)

I'm wondering what aspects of the sound are actually changed by the enclosure and by the driver, NOT theoretically, but in experience, like in this case.

I'm just too stubborn to believe that AKG stopped caring so much and the K-701 is not an improvement from K-500. Do more K-701/501 owners think it that way?

I think the reason why you got your K-500 so cheap is cuz a lot of people underrate that can, I wish I could compare 701 vs 500 any review would be appreciated.
