What the hell -- the reviewer complained that an open back headphone leaks sound. That's like someone reviewing "cars" and complains that the truck they're reviewing is too high off the ground.
Replaced my iFi Micro iDSD Black Label ($600) with a Topping D90 DAC ($700) and an iFi Pro iCAN ($1800), which will be my endgame rig. The GS3000e had some hiss at a moderately loud volume with the iDSD BL. With the Pro iCAN, it's silent unless I turn it up to dangerous levels. Still, I wonder if the remaining hiss could be removed by converting my GS3000e cable from 1/4" to 4-pin XLR. Perhaps it's worth a shot...
Balanced outputs on a short (~10ft or less?) cable to headphones / speakers won't improve the noise to you headphones themselves at any perceptible levels (of course you do get more voltage / power to them, though). The only way it would make a difference in the hissing / background noise would be if the output circuitry in the amplifier is actually quieter running balanced vs SE. Balanced makes a difference in line level signals because they're low voltage / higher impedance and then get amplified, which in turn amplifies any noise picked up by the cable. But since the output from the amp is much higher voltage than any induced noise (EMF or RFI) it shouldn't be audible.
Hope you get it all cleared up! All that gear is beautiful and I hope to hear the GS3K someday. Gonna have to wait a while till the kids grow up haha. Maybe by then I'll have a dedicated listening room for my stereo system, too!
The D90 DAC is dead silent, as I don't hear any hiss when I plug it into the Micro iDSD BL in battery mode. (If the Micro iDSD BL is in USB mode, there's a significant amount of USB power noise.) So I ruled that out. The XLR interconnects are only 1.5 ft; the D90 and Pro iCAN are side by side. The Pro iCAN is already at 0dB gain, but I just want to be able to turn the volume dial all the way without hearing any sort of noise whatsoever. So I'm thinking that the SE implementation of the Pro iCAN isn't the best, and that it's better off to just use the balanced headphone out.
The low impedance and lower sensitivity of Grados compared to IEMs makes them a little tricky to amp properly.
The total cost of my rig (GS3000e+D90+Pro iCAN, $1800+700+1800=$4300 USD) is still less than the MSRP of the Abyss AB1266 or Stax SR009S or Sonorous X. I think I struck a fair balance between budget and sheer insanity, especially by going with the D90 over the Pro iDSD.
I think you're the first person to say the 325's have muddy highs lol. I always thought the 325s were the harshest in the treble region!
I hope you will have a wonderful weekend You are always on the search of something better sounding. I am somewhat slower, and you are my reference for comparisons with for example GH2s....I am back in my Grado GH2's after a long break (I just spent 21 straight days listening to my new Focal Elex's with all my amps).
I have been curious for a long time about tube amps. Since most of my headphones are of the very efficient variety, I decided hybrid tube amps were the way for me to go. That path did not end well.
I did lots of research on low impedance tube amps. I actually narrowed it down to:
1) Mapletree Audio Design and their Ear+ HDII
And
2) Hagerman Audio with the Tuba.
I ended up choosing the Ear+ for two reasons: I really like the idea of buying Canadian and it was $200.00 cheaper.
I have pics and brief impressions on that thread as I just started using it today.
For the weekend I will only be using the Grado's. The vocals are Amazing and the guitars, horns, etc. all sound great and separate.
This amp is not thick and bassy. It is clear and clean and I now understand the description "airy".
I am very curious to try my other 'phones, but this combo is Really working me. My biggest fear with this large (for me) purchase was that it would sound like all my other amps. It definitely does NOT!
