Is the noise difference measurable? I have enough room in my Carbon to add a GRLV, but wonder if it's worth the hassle.

I want to hear these for a few weeks in my system, but this is the first dynamic since the HD800 I'm really excited about. I thought I was beyond hype, but I ain't. I wish they weren't $4000.

I'd like to hear them, a little. I have no interest in "upgrading" my very comfortable and great sounding HD800 for a tiny improvement that I might or might not really be able to hear. I especially have no interest in paying around $3200 (cost of Utopia minus what I might be able to get from selling my HD800) for the privilege of "upgrading".
November 2, 20169 yr I will say that there are better deals than MSRP out there if you search. There is no way I would have spent $4,000 on the Utopia, good as it is. It is quite a departure from the HD800/800S. If you've been using the Senn as a daily driver, the smaller soundstage of the Utopia does take some getting used to. That being said, my Utopia "demoted" my 800S to office duty.
November 2, 20169 yr I could buy a lot of different things I'd rather have than a small increase in performance.

November 2, 20169 yr surprisingly the GRLV power supply makes a bigger difference than I had thought.
November 2, 20169 yr Interesting. And tempting. I don't have room for another transformer in the case. Would the 16-0-16 VCT 500mA winding I currently use to power the 7815/7915 be adequate to drive the GRLV for +/-15V outputs?

November 2, 20169 yr Just now, gepardcv said: I know, but I was wondering if the input voltage would be adequate. you need 6V for drop, and you have 22.6V

November 3, 20169 yr Apparently no one else would neither, eBay has zero history of them ever being sold. I need to sell mine , I never listen to them. But yes , as of yet , I still have them.

But yes , as of yet , I still have them. I think they are the rarest of any Grado beside that "free-style" system. Should be able to bring in $3K to 4k. I remember John Grado was listing them on ebay at $3500 couple of years back and he sold like five or six pairs of them. I would rather keep the L3000 instead of the PS-1 however.
November 3, 20169 yr 13 minutes ago, Dusty Chalk said: Yeah , exactly, I still have the L3000, don't intend to let that go. Still using them? I miss mine.
November 3, 20169 yr Plus they're awful! Like getting fucked in the ear with a dog dick. The PS-1s on the other hand I covet, as you know.
