Mapman,

Mapman, yes, as the footnote confirms it was a conrad-johnson Premier Four. |
Atmasphere, until I see more compelling evidence, or get a free trial, I'm not spending my hard earned money on something like this. I don't hear the need. |
Atmasphere, could you please elaborate on these; "...non-linearities caused by capacitive elements in the junctions of the output devices."? |
Atmasphere, how is this "non-linearity" measured, and at what level does it become an issue? |
Mapman, you might find this interesting:

Atmasphere, you have still not convinced me that your opinion is a fact. That I have always preferred systems that have amplification driving loads under 8 Ohms to those with amplifiers driving loads over 8 Ohms, leaves me to doubt these assertions. In the end, the final sound is what counts, and at least to my ears, that holds true regardless of whether one uses sensitivity or efficiency as an amplification guide line. |
Mapman, I suspect that in narrow technical terms there might be something to it, but I wonder if it would hold up in broader technical terms. More importantly, I agree with you, that in practice it might not matter. |
Mapman, I am not convinced that a higher impedance is a technically better playing field. In fact I believe the opposite to be true. |
Mapman, One of the advantages of ss amplification is it's inherently low output impedance, low speaker impedance speaker loads are almost never a concern. There are some, that believe that the best results occur when impedance's are more closely matched (Jeff Roland?) rather than having a low to high ratio. I suspect it might have more to do with application. It appears to me that it is much easier to achieve better bass response and steadier impedance loads in lower impedance speakers than in higher impedance speakers.

Atmasphere, auto-formers aren't a new concept. The only ss amplifier I know of that includes an auto-former appears to do so in an effort to adapt to an otherwise speaker mismatch. If auto-formers were of such benefit and without deficits, why wouldn't they be included in all original amp designs? Or if not amps, why not original speaker designs? Of course we don't listen to amps, but speakers powered by amps. That para-phrased statement of Mr. Norbert is quite a bit different than claiming that ss amp sounds better into higher impedance loads.
What aspect of the speaker cable is this attributed to? |
Atmasphere, silly me, I forgot about the Macs. I was referring to the Pass M2. |
LOL, Atmasphere, I've got hand it to you, you do know what you like. The Ridley runs hot and hardly increases power much at all into lower impedances. Just like yours. |
Minorl, all good points, but, I do agree with Atmasphere on the point that in many instances one technology will work better than the other, and visa versa. In such instances, one or the other can not be swapped in and out and be expected to work at their best in such varied systems.
Obviously, this often compromises direct comparison, and one has to ultimately decide what pro and cons of the total system, best suit the individual consumer. |
Magfan, You might appreciate this advise:
