Well I questioned your claim about the need for an amplifier with a low damping factor of 10 for it to be audible. If you use higher than 14 AWG you get close to 1 dB error when using an amplifier with a DF <100 connected to a 4 ohm load.The only (speaker) amplifiers that have such a poor DF are some tube amplifiers or 'specials' and in such case that poor output R is part of the 'charm' of the amp.
Those amps usually are not recommended for speakers dipping to 2 ohm in the bass area anyway.
Combine that with a wild varying speaker impedance and long or thin cables and yes it will be audible.
In practice most amps are above DF50 and people using speakers that dip that low use short and thick cables anway. Certainly when they are enthusiasts.
But... this thread is about DAC sound signatures and has no relation to speaker cables so perhaps discuss cable resistance in one of the many cable threads.
Is that a diagram of how Mastodon works?
It certainly avoids the main issue of controls.Is that a diagram of how Mastodon works?
Thanks, but no need for Google Translate - I have no problem reading Swedish. That picture doesn't help us much. Sure, it is a standard before/after switching setup, but it doesn't tell us anything about how levels were matched, and if the listening was single or double blind, or what statistical controls were used.Google translate is your friend.
Yeah. Then maybe we can understand why someone would run tiny wires to a speaker they care aboutBut... this thread is about DAC sound signatures and has no relation to speaker cables so perhaps discuss cable resistance in one of the many cable threads.
In other words we'd want the specific (and detailed) test descripition of the specific tests you are referencing. Not a generic description of a double blind test.Thanks, but no need for Google Translate - I have no problem reading Swedish. That picture doesn't help us much.

Of course, but it matters.In your first example output impedance (amp plus cable) is dominated by the amplifier.
In your second example, it is dominated by the cable - but only because you've changed your gauge from a reasonable 14awg to a less useful 18awg. In other words - thin lamp cord.
The only important rating of speaker cables is resistance - as long as you select low enough, then cables don't matter. I don't use smaller than 13, my current cables are 11 (2.5mmsq and 4mmsq)
It's audible compared to it not being there.Whether or not that error is audible or consequential depends on the impedance differences of the speaker. When that is fairly flat it is only an overall level difference and inconsequential.
Besides it has nothing to do with DACs.
You really need to start a cable thread with that kinda stuffOf course, but it matters.
DF = 160 returns an error of 0.5 dB (14 AWG)
DF = 80 returns an 0.7 dB error (14 AWG)
DF = 60 returns an 0.8 dB error (14 AWG)
It's audible compared to it not being there.
Which is easy to eliminate by having even length cables and going up in cable size and/or choosing and matching speaker and amplifier.
And most speakers have uneven impedance with peaks and troughs. I don't think I have ever seen a flat speaker impedance curve..?
It has nothing to do with DACs though.
Just responding. I want to stop.You really need to start a cable thread with that kinda stuff
Uh huhJust responding. I want to stop.

I'm sure one of the moderators can help you with that.Just responding. I want to stop.
It takes two to tango. We'll stop.I'm sure one of the moderators can help you with that.
The math seems off.Yes, DF being a product of output impedance and load impedance (cables included). Worsens with low impedance loads. My calculations with an amplifier with DF=10 and a 4-2 ohm load, 13 ft 14 AWG cable returns an attenuation of max. 3.12 dB. 18 AWG returns 3.42 dB error.
DF = 160 returns an error of 0.9 dB (18 AWG)
DF = 80 returns an 1.1 dB error (18 AWG)
A very unstiff power supply regulation for an OP-amp : slightly higher distortion at full music levels, current clipping in extreme cases, possible lower power voltage driving the OP and for sure some minor compression sound effects . In the original Linn akurate DS the output OP amps lm4562 only have 9 volts because of this - read more here:
I doubt it was the reason . Its a very expensive player. They use a very soft power supply ( If you read the whole modification thread you will understand.) The reason for this is probably to gain less noise, and (maybe) to have a softer more mellow sound. The power supply in the Akurate DS is so soft it collapses from 16 V to 10,6 volt , and after the regulator its only 9 volt.They had only 9v feeding them because that's the voltage linn had to play with given the penny pinching decision to continue using one of their existing smps, it wasn't a musical choice, it was a fiscal one.
Uh huh.I have tested driving lm4562 and the opa2604 with low voltage and the dynamics are clearly better with 15 volt. This is my (limited) experience .
