Thanks as always, for the predominately insightful notes… albeit, 100 wpc isn’t 500 or 550 wpc. I do appreciate the efforts and time though

One practical part of this all is to have an enjoyable, user friendly exp. Not long ago I had a 250-400 wpc amp, w/26 db gain, and a pre w/23 db gain. I still have the pre…
The outcome with reportedly 89 db 6 ohm nominal’s combo did not allow for sweeping movements of the vol knob. The useable range of the knob became vastly reduced to an arc of around 20% of it’s normal span… or less.
This made for a tad more tedious use. Only little very quick zaps on the remote could be had to adjust the volume, thus very fine, precise sound levels may or may not be had. By the time the vol knob was at 10 am or so, one needed to be outside the home to prevent hearing loss with extensive listening periods. Normally, I’d not get much above the 9-9.30 range routinely.
That past exp while producing some really great sounds, hampered the exp with me always having to worry with getting to the ‘just right’ listening level… and of course, the ever present worry I could somehow nod off and somehow spin the vol up inadvertently some great degree and damage the speakers.
I see some wisdom in having finer control of the vol. Higher powered amps in my past reduced this greatly. I don’t recall getting my vol past 2pm in fact… and that’s a far cry from only being able to move it from 7.30AM to 9-9.30 before it’s very loud, and at 11 it runs you out of the house.
I figure impedance played a part in that scenario too. The BAT amp purported 100K… 50 + 50 on the xlr’s. I was only running RCA via adapters so 50K ??, back then.
The Wyred 4 report 62K roughly. Not sure as to Rowland, with some sort of imp matching device inline with the gain section.
My tube pre is 400 ohm output. My Onkyo Rec … well I’ve no idea but I’ll guess it’s higher by a good bit, given how it and the tube pre act with my SS amp… which may or may not make good sense to compare things that way.
Anyhow, I’d sure like to keep using at least half of the volume dial… not just 10-15% of it. I’ve noticed this vastly more sensitive vol knob action with SS amps having both high imp (100K) and good power, 150 to 250wpc into 8 ohms…. The higher the power the less I can move the volume knob.
Consequently, a 600 or 1000+ wpc into 4 ohm amp does imply a similar circumstance may well prevail again, were such an amp (s) be employed… or does this not reflect high powered ICE amp implementation?

Not being the sort that unquestionably takes the notes of any reviewer as golden, I look for supportive comments from other's I trust more... here. Hemce my posted concerns.... duh.
