I've Just Learned What Amplfier Bias Is...
Hi Klaus,
Bare with me here as I’m a newbie and am just learning about asking YOU the right questions, before I give you a call as I just read the 12/10 six moons review of the Odyssey Kismet Monos along with the 11/10 audiocircle forum of Kismet vs Extreme:
https://6moons.com/audioreviews/odyssey2/1.html
https://www.audiocircle.com/index.php?topic=88089.0
So to make a long story short. So far I (think) would like to purchase a lightly USED from you Khartago Stereo Extreme + biased to every conceivable variable you can think of that I may need for my particular system and room specifics.
Am I ready to buy now, no but I’m working on it.
One of the interesting facts is this morning I’ve spent about three hours trying to figure out why and how folks with high end audio gear use components WITHOUT tone, treble and bass control in the sound chain.
What I’ve read this morning and come to understand is it’s because it’s best to get the amplifier manufacturer or DIY biasing of the amplifier for the best resolution, soundstage, imaging, speed, fidelity, tonal balance, holographic three dimensionality, neutral and dynamics - spot on - in the listening room itself and completely compatible with my gear.
Bare with me Klaus, I’m getting there.
Was there supposed to be something in there about bias? Maybe you forgot to include it? Because I'm sure not seeing it. Was it anything like this? https://robrobinette.com/How_to_Bias_a_Tube_Amp.htm |
@millercarbon Good question MC, from what I gathered bias is ’something that can be dialed in an amplifier that can be HEARD. You’ll need an inexpensive voltmeter to measure the levels and a non-conductive alignment tool but with a little experimentation and practice it can be done in 2-3 minutes per amplifier. Bias level pots are the ones near the big central caps, the offset pots.’ This is per Nicholas Bedworth of six moons. My background is structural, concrete, structural steel and rebar. Electrical engineering was not part of my informal training but believe it or not, with folks here on agon like millercarbon taking the time to help and explain albeit NOT in layman terms what things in audio are - like bias, some of this stuff is making sense and finally sinking in. Even if it’s only on my terms of understanding. I guess I had a aha moment and not learned (at first) what it is, but with a solid state amplifier I learned HOW TO ADJUST BIAS MYSELF with an inexpensive voltmeter we all have around the house. Also keep in mind I’m a newbie trying to share with other newbies in newbie like terms. Although with my structural background I could probably design one heck of a mean concrete audio stand! With characteristics very similar to the look and finish of those concrete kitchen countertops you see in the magazines. millercarbon I must say I was surprised you gave a wikipedia, cut and paste like answer! That is entirely not like you! :) Thanks millercarbon for taking the time to help explain what bias is. |
