Mr. khiak
Thanks. What a post to start my weekend with…Please be kind to thank in person your dear friends: Sam and John. Posts like yours are the best reword to my effort to bring this subject to your attention. It really makes me happy.
Some comments on the sound impression.
I assume that the DIY cables got the lows to sound more realistic. The Wilson Alexia driven by Passlabs 350.8 dont need a pair of Rel 212se to get the bottom lows alive! The note that the DIY cable brought in the bass (detailed and tight) shows that the AWG of the DIY cable was way more "right" than the previous Kharma. When you emphasize one band (the low band in Sam's case) the other bands might seem to have less. Often happens when a speaker is positioned wrong and has too much bouncing bass from a wall or a corner. Not as it is really has less highs. As Sam's impression is: "The high extension seems to have lessen and sounded less sparkle, but sufficient and overall adequate". Just the Fr. Response is more realistic (flat). What you describe as sweet, is like having more of a tube sound: poor DF. A poor cable can do that to a fantastic SS high DF amp. Some do like more the "Sweet sound". However, the realistic is better to my opinion. I see to yours too.
Same impression is repeated by you, just to give those words more weight.
In overall, the #4 AWG DIY (calculated) cables got your Amp's into full control (using most of the Amp's DF figure in use). It is another proof that science prevails over none science methods. It also increases statistics, to get the result more accurate and firm. By your testimony and the spirit of your words (all six), it shows that a small try of the idea offered for free, goes a long way when it land in your room and plays the music.
Could you please say:
a. What was the length and gauge of the Kharma and Ansuz (the once replaced by your new DIY cables)?
b. How much did they cost?
c. Could you get some pictures of your cables (mainly of the endings).
Thanks.
I'm here for now. If I move, I'll leave a trail to keep helping those who may ask. Thanks again for the sharing.
