Are there any differences in sound quality among the two interconnects advertised in this thread?

How do you get rid of the hissing?

 

[Chris_Himself]

you cant, hissing is one of the natural qualities of some amps, and so is the turn on thump.

There are two ways to get rid of hiss:

- use headphones with a higher impedance
or
- increase the impedance of your headphones with an impedance adapter (building instructions are somewhere around here, it's basically two resistors plus wiring)

Out of curiosity: Which headphones were you using when you noticed the hiss?

 

[Zorander]

I haven't noticed any hissing with the PX-100. I also put on the MS-2 for a little while and did not notice it. Guess I'll try it again and look out for the hissing.

If I were you I wouldn't try and look out for it, it only lessens the enjoyment IMO. Why look for a fault if you can't hear it?

 

[Kryosphinx]

I hear it a lot with jvc marshmallows. I hear it to a lesser extent with KSC75's. I'll look into the impedance thing.

what source, and what IC are you using?

Hey there! Can I get those pictures? ^_^

Hey Kramer, have you had a chance to write up a review on your Sweet Pig? How does it compare with your other amps, especially the Microshar? I'm thinking of getting The Hercules Sweet Pig.

Just enough to make me feel like this thing isn't made of cheap material. The outside edges are all smoothed over, however, the inside edges on the face and on the back aren't smoothed at all, and so they're kinda sharp. Nothing a few quick swipes with a knife won't fix. There isn't any rattling inside when it's shaken, nor is the sound affected. The in and out jacks are solid. No rattling or give. The volume knob is very smooth. This thing provides plenty of power for my headphones (KSC75's). I keep the knob 1/8" from off. I tested the amp with some generic 2.1 speakers. It worked fine. Sounds significantly better than my computer's onboard audio.I've only got a few little problems with it though. There's a "pop" when it turns on, and it only turns on when there are two plugs in the jacks. So if I'm already wearing the headphones, there's no way to avoid a popping sound to my ears. Also, the power jack is somewhat flaky. When it's plugged into the wall, if you move the jack/plug around, the power blips on and off. If you're listening to music when you plug the power source in, there's a split second when the amp is switching from battery to wall power. If I take it out, I have to move either the out plug or the in plug to get it to turn on using battery power. If I don't touch anything, it'll just stay off, even though it's plugged in.

How about the hissing sound that Skylab reported in his review....did you get any of that?

No. Dara sent me a link to Skylab's review. He thought that for the CURRENT price, it was a very good buy!! Two problems: the POP when turned on that some of you have already discovered; and a hissing sound at all volume levels. Thanks for the review, Skylab.

ZVM Line-out. I've got a homemade IC from Radioshack parts. 22GA stranded copper wire, gold plated connector, modified ipod dock connector. Soldering is solid.

Yeah, I get hissing with my JVC Marshmallows and minimally with KSC75's.

 

[choomanchoo]

Hissless here, but only because, I'm deaf in that particular sound range, not sure technicaly what type of deafness it's called, but it does exsist,



no, serious

I'm really interested in getting one of these while they are cheap, just wondering though, will they do a good job handling a pair of HD580's? I have a pair of Grado SR-60's now which should sound pretty good, but I am planning on getting a pair of HD580's in the future, will this be enough to power them adequately? They will be run out of a Zen Vision M and an older pioneer cd player (mini to rca cable connection). Thanks.
