For some reason, posting links to the following threads hasn’t worked the two times that I have tried. So I will post their titles instead:
1) Best amp/preamp to go with SL?
2) Atma-Sphere MA1 3.2 vs Pass XA60.8 amp
There are interesting and informative comments about several amplifiers in these threads, including several that I made about my SoundLab amplifier sojourn.
Hence, there was no need to reiterate my same comments herein and I responded to the premise of amplifier rolling (if you will). Having more than one amplifier would be a luxury both fiscally and physically. But I certainly can’t fault the premise, if one has the wherewithal and desire to switch now and again, for whatever reason.
