If you play your music between 10 and 12 on the d

If you play your music between 10 and 12 on your volume dial, does it sound better,same, etc. depending on the wattage of the amp? Say a McIntosh rated at 250 wpc compared to a McIntosh rated at 75 or 100 wpc? Does the quality of sound go up with the wpc when you listen a lower levels? or does it stay the same?

Everything else in the system being equal Cdp, speakers,etc.
It depends on the preamp, amp and speakers.

10 to 12 on the dial is not universal fot what you are describing, which as far I can tell is when the sound fills out completely with good dynamics and extension.

The ideal system plays as well at low volume as it does at high volume. I have never had a system that did this. All my systems have had a certain point on the preamp's volume knob where the music came into full bloom.

Depending on the speakers and amplifier, higher wattage sometimes adds weight and bass at lower volumes. In a high efficiency system, I don't believe this is true.
all equipment being equal, if i understand your question, in selling equipment all my life, turning it up always caused me to ring the cash register. now in saying that, i don't know what all that means, does it mean that we just like LOUD? and we also like BIG.....so to answer your question, i am not an engineer, especially an audio engineer, but i do have a understanding of what music should sound like in volume levels. the music being played should always sound as if you are listening live, how can you listen to rock , at low volumes, you can't ....nor can you listen to jazz loud...it must be moderate or you change the music. it always gets me how some people listen to music at one volume,low,med,loud,instead of listening as if they are in a music hall, club, theatre, always listen to level that you would think it would be played live. now to try to answer your question...in owning many, many amps, i always liked power, being, tube or solid state and i always tell everyone to buy as much clean power as you can afford.....dwhitt
Is this a question about the ideal impedances for the attentuator? I always thought rightly or wrongly that the attenuator performs best when it is past the 10 o'clock position - it is certainly true with a passive - not just a matter of loudness which depends as much amp and speaker.
I'm demoing a passive. It sounds best at 1:00 and beyond...all the way to full throttle.
I know that in a passive being beyond 12 is really recommended as the output impedance gets lower and lower. Not sure if this applies to actives, but I think it might.
Anything past 11 should be ok. Basically volume controls are not great when attenuating enormously. Some resistor ladders are very good though. Pots are usually bad at the extremes and it is better to play past 11 with 1PM being pretty much gauranteed to be good. Usually the problems are greater to Signal to noise and poor calibration in sound between le and right channel at low volume extremes...
If you have a stepped attenuator, you get better discrimination of levels if your "normal" listening level is around "noon", since each step is a smaller percentage of your volume than if the attenuator is just one or two notches up from its lowest setting. You also have a better signal to noise ratio. On the older Audio Research amps, which had level controls, ARC always recommended that you set the amp gain so that your pre-amp gain attenuator was somewhere around noon for normal listening levels (and that left you with a lot of range if you wanted to melt your speakers...)
I know one thing for my listening...having more, and cleaner WPC, almost always seems to articulate the music better over all the volume spectrum...that's if, of course, you have half-way good speakers, preamp, and other stuff,etc. I have 600 WPC. Do I need it? Probably not, however my music sounds articulated and clean at all levels, especially at low, soft levels. Your system's volume control is pretty much relative to your system. At 10 or 12 my music would be sort of loud for the room and my tastes. Loudness and articulation are definately two different animals i.e., nothing is louder and more obnoxious than a fully turned up boom box...it's plenty loud but no articulation.
Sure this is the sweet spot, but I find that some of today's digital gear puts out so many volts, that I end up with my analog preamp's volume at the low end of the scale.

I pretty much solved that problem by only playing LP's in my main system, but the new the new PS Audio DAC coming out in the next months claims to have a digital volume that does not degrade at any value above 50%. I am thinking this will be ideal to allow our analog volume to be optimized, and adjust the digital to get everything into it's sweet spot, for any given desired SPL from the speakers.
Just the opposite for TVC's, where output impedance rises with less attenuation. S&B TX102 @ 1KHz: .14/-40dB, 14/-20dB, 1.4K/unity. That's why I use high gain (38dB) amps with them. Input impedance is more favourable with attenuation too.

I have CD's that are "loud" at 1:00 and others at 10:00, depending on the recording level.
