Recently upgraded to this from a Sumiko Blackbird MC HI. Wow! Simply Wow!
This cartridge insists on almost perfect setup. Tracking force, alignment, azimuth, etc. Do it twice to make sure things are perfect. Hell, do it three times. You'll be rewarded.
Channel separation is rated at +35dB. That's a crazy number! It results in stereo sound-stage imaging that is simply sublime. Admittedly, I'm a sucker for this. I LOVE recordings that take full advantage of both stereo placement and dynamics. The Kleos does both in spades!
I had my previous cartridge, the Sumiko Blackbird, super dialed in. So much so in fact that I really felt like there wasn't anything more to get from it. It sounded crazy great and dug out new detail from songs with which I was intimately familiar. It's a wonderful cartridge for the money. But after upgrading some components (Pro-Ject Tube Box II => E.A.R. 834 P => Manley Chinook) I began to wonder just how good sound could be. Pro-ject to E.A.R. was NOT a subtle change. It was amazing! E.A.R. to Chinook less so, although it improved detail noticeably. I came to the conclusion that if more benefit was to be had, it was time to upgrade my cartridge.
I agonized over this for months. And ultimately came down to 4 possibilities: 1) EAT Jo No. 5, 2) AMG Teatro 3) Kiseki Purpleheart 4) Lyra Kleos
Finally it was a close race between the Purlpeheart and the Kleos, but the engineering part of my brain decided Kleos, mostly based on it's channel separation specs. Did I mention I LOVE stereo imaging.
Setup was fairly easy, although I tweaked and and re-tweaked for the better part of a weekend. I'm at 265 Ohm's loading and 1.74 gram tracking force. I've messed around quite a bit with the loading but keep gravitating back to 265 Ohm's as sounding best on my system.
So how does it sound? Well, more detail. This thing is revealing to say the least. Mostly good (detail I've not experienced before) but a bit bad as well (any sort of surface noise or dirt on the LP is equally revealed). A quality tone-arm cable is a MUST and it needs to be uber-shielded. I was running the same AudioQuest Colombia interconnects from the TT to the preamp, and experienced a bit of low level / volume hum which initially freaked me out. I put in a pair of Synergistic Research Core 2.0 tone-arm cables and am floored.
Everything is tight, right, and out of sight now. Love this cartridge.
