  • Sozo Cap test part II - w/Wav files and a 50+hour burnin

    Ok kids, let's try this again. Here's my test rig:

    EJ strat into my PC, direct. Made a 320k mp3 file of that dry/clean guitar track, put it in my iPod.

    Plugged my iPod into an 18 watt marshall, recorded three times so far:

    1) amp with mallory caps
    2) amp with Sozo (new) caps
    3) amp with Sozo (after 50+ hour burnin) caps

    Reason why I plugged in the ipod was so I would have the exact same input each time. Didn't move the mic, used same recording settings also on a Korg D1600 multitracker.

    Each track was burned from the D1600 to wav file, then those wavs were edited in Adobe Audition to only cover the 'back in black' part of the clip, due to the size of the files. This took out extra A/D D/A or whatever steps, including being converted to MP3. These should be a little more hi fi than the original MP3s I posted in threads earlier.

    Anyways, here are the clips:





    Note: files aren't in any discernable order, feel free to guess what is what. I'll be more than glad to give my two cents and reveal what is what *AFTER* people have discussed it a bit - I don't want to show my hand and then have people pro or anti Sozo get their licks in.

    I know the playing isn't that great, and the clip is quick, but it's the best comparison I can give - I'd recommend anyone who builds many amps should do something like this, just to be sure you're using parts you like. I'm starting to consider buying a set of Orange Drops now... and a different output transformer. Jeez, this is almost a sickness.

    1 Sounds most lively to me...Really notice the overtones when you give that A note the wide Angus vibrato shake in the little descending pentatonic lick...

    3 A bit less...Almost like you turned the tone on your guitar down.

    2 The least...Like you turned your tone down even more

      Seems one sounds fairly best to me. Although it could just be the perceived loudness over the others.

      Then three. Nice as well, actually seems more succinct and has more dynamics than one does really. But one seems to stand out...

      Then two is considerably farther behind...

      I listend to this on a pair of Tannoy Nearfields. Not the ears are much good these days...

          #1 is best
          #2 is fine
          #3 has the blanket over the cabinet sound

            Wow,
            You guys are good. After reading what you wrote about #3, I think i can hear it.

            I had to listen to each 3 times. #1 is slightly better. If i heard this in a casual setting, I don't think I'd notice.

                I'd rate them 1, 3, 2 in order of preference. 1 stands out more because of the highend, and is louder than the other two. 2 seems to lack dynamics, a little harsh. 3 is dynamic, yet has less highend.

                I can't make an experienced guess on what is what because I don't know anything about the effect of burn-in on caps. I know what it can do to headphones...

                My wild guess would be that the files are in the order you listed above... 1=mallory, 2= new sozos, 3= burnin sozos

                Because 1 seems to be louder, and the other two are fairly alike, but 3 is more alive than 2 with sweeter highend and more bass.
                However I may be on a completely wrong road here... just a guess without any real experience in the field.

                BTW, I listened to all the files multiple times on Yamaha HS80M monitors and Beyerdynamic DT770 headphones.
