I suspect your routine for playing a cut on SACD will go something like this-insert CD- power down player- power up player- remove CD- insert SACD-go to cut- play for 12 seconds- press repeat -listen to the cut
Follow Ups:
I take out the record, put it on and play it. Only if I just got it used and it is visibly dirty will I clean it. Otherwise it is easy for me. I hate tweaking and messing around. Every once in a while, I need to level the arm, but that's easy as well.

And chosing not to hear those absolute polarity and track-repeat problem because of the disruption to continous musical flow is very wise. Vinyl listening requires only minimum rituals at the start to get them to sound satisfactory, unlike digital which needs repeating at the start of every track. I don't propose powering-down prior to playing every track of course. Then you can go on listening to vinyl without being disrupted for at least 20 minutes. And in the same regard, listening to classical music on radio is even more convenient. You don't even have to cue the needle, get up to change to the other side. If convenience is your thing, then listen to radio. Actually, you are already hearing the jitter problem on digital. It is just that your system is masking the effects and not allowing you to define what exactly is wrong. After track-repeat, digital does sound more like vinyl in its portrayal of the music's rhythmic flow. Methos hears it. Richard Kern hears it. A lot of people here in Singapore hear it as well. The degree of change which they can hear varies from system to system, according to their system's inherent neutrality and the amount of tweaking (actually, less AC tweaking, the better).

I have one of those little Tivoli Model Ones. Sounds great. I have always been a big listener and supporter of college and public radio stations.As far as absolute polarity, I can change it from my remote. Rarely does it make an audible difference. Sometimes it does a little, strangely enough I find this only important on vinyl and only of minor importance there.
Though it wasn't the case from the beginning, when I was still using the Powersnakes powercords. As the late Lars had reported, the problem with absolute polarity is often record-label specific. Some record labels' are found to more prone to releasing recordings with inverted absolute polarity. But then the same recording released on another continent can be found to be corrected. This is no doubt due to the differing standards of balanced terminal wirings in the production chain. If you ever get hold of Carol Kings' Tapestry stereo SACD and LP from US and Japan, you will know exactly what I mean. The inverting happens on alternate tracks, and the same order is reversed when comparing between the 2 countries' pressings.What is preventing you from hearing the effects of polarity changes on your digital gears is probably also preventing you from hearing the jitter problem and the sonic improvement that the track-repeat procedure can provide.
The laser adjustment is an entire new issue not related to these 2. The effect is very subtle, "thinner than a dog's breath" is probably how Jonathan Scull will describe it. So it should not be a concern to you.
"What is preventing you from hearing the effects of polarity changes on your digital gears is probably also preventing you from hearing the jitter problem and the sonic improvement that the track-repeat procedure can provide."Totally agree. Could be the room. Could be my ears. At any rate, if I end up getting a Meitner DAC or something like that, there will be a big audible difference and those are the things I care about.
Absolute polarity- pet peeve- there is no "correct" polarity, no "incorrect" polarity. There is no manufacturing standard for this, so close to 50% of releases will be one way, 50% the other. Neither way is right or wrong. And as you say, different tracks on the same recording can be different as well. If it is important to you, it is best to have a switch to use. Otherwise you need to adjust as necessary. You should not condemn some recordings as "inverted". About half of all recordings will fall into this category. Without a standard, it is just a toss of the coin in all cases.
I will enjoy my radio, of that you can be sure. I am a "radiohead" from way back.
