And now my HD800 and HD650 sound like unclear over dampened garbage.There is really something about driving a low Z headphone from a low Z source. And bonus if the headphone has minimal dampening and no to very small pads.

Maybe you just got the synergy part down for the Koss headphones.

That Koss KSC75 is better than most people think. Get a K500/K501 with a good amplifier and you know the difference AKG madness makes. When you are broke, Koss saves your wallet.

Post this in the For Sale section of the forum

On the other hand, if I were to introduce counterpoint, then yes, there is very smeary and homogenous sounding gear that can blur voice leading by ruining transient attacks. There are a ton of much more expensive headphones than the KSC75 that are far more guilty of that though :)

@ColdsnapBry orthos have zero texture? You’ve been listening to some crappy orthos!!! They are full of texture.

Now a thread. Discuss!!

This is (one of many reasons) why this community is spectacular.

I live in France. Tempted

Now sold.

The original PX100 was nice. The mark 2 was also nice. The sweet spot was the PX200 II, basically a baby HD25. Thing was, the KSC75 and PortaPro combined were cheaper than a PX200 II. Koss offered more value for money...

@Deep Funk My friend uses the PX100 a lot and I suggested he try the Porta Pro, which he thought sounded like a tin can in comparrison. Which I always thought was strange because I've never heard a tin-like sound out of a Porta Pro, always found it very smooth. How about you?

Both warmish with kind of booming bass. Not bad for portable use to be honest. The difference must be the drivers and how they render the frequencies. The PX100 and PX100 II were at one point difficult to find at retailers (I do not know why) so yeah PortaPro.

I get too much bass boost/bloom with Clear/Stellia on high Z. Would expect similar with Elex due to similar impedance curve.

Don't hear any difference in HF timbre.

With Elex, I prefer high Z, less dry.

Seems like a preference thing! I find Elex too try on low Z, agree. I think Clear and Stellia have a bit more bass than Elex, so that makes sense to me!

@YMO I can definately see this, I think for my taste I like a bit more bass and a bit of a rolled off top.

Both are great combos. I use Jot 2 instead of Asgard 3; it’s a little more aggressive which I think works well with the Aeolus

@jnak00 I have a Jot 2 and agree it's a good pairing with the Aeolus. Agree with the more aggressive nature, it wakes up the Aeolus. My favorite pairing there is Jot 2 balanced in balanced out and on high gain with STOCK universe leather pads. I prefer suede pads so I bounce to the Asgard 3 for that combo or do Jot 2 with 1/4" out on high gain.

@Azimuth Yea true. Ok. I might get a device like this then. I really do hear a percieved loss of dynamic range when spitting.

My dynamic range when spitting is only about 8 ft.

Output device has a fan-out drive limitation. The two amps may have different input impedances which combined causes some issues with the output device.

When I had my sw51+ all my other SE stuff didn't hum, it did though. Apparently it didn't for the people it ended up with but I was honest about it. Think it's with an SBAF member as well.

@HotRatSalad Gotcha, I wouldn't have noticed the hum if I didn't have closed back headphones. So maybe the buyer just stuck a HD6X0 on it and was happy.

Many amplifiers have some residual AC mains hum. More sensitive headphones may make hum audible while lower sensitivity headphones mask hum.

Some designs are more sensitive to external fields: https://www.superbestaudiofriends.org/index.php?threads/transformer-hum-source-unmasked.12010/

Hi @Ksaurav402 , an older black silk HD650 and I'm looking for an HD800 at the moment. I have a ZMF Aeolus too, but HD650 is getting all the headtime lately.

Where's the best place to get a crack built and how much ?

@HotRatSalad I'm using James from Etsy for this build. He's been extremely accommodating and flexible with my requests:

https://www.etsy.com/nz/shop/TheHeadAmpBuilder?ref=simple-shop-header-name&listing_id=623367926

He charges $375 for basic crack.

I did not know what this was and someone posted on the ETA Discord that one is for sale on HF.

I've long suspected that they're similar sounding amps, but I expect the SW51+ to edge ahead. Looking forward to hearing your impressions.
