I have encountered only one quality issue. Regardless, it is customer service that really counts. Several years ago, I had a failing Krell…it was a rather old model amp suffering its age. The folks at Krell couldn’t have been nicer or more accommodating and I had it totally refurbished by them (reasonable cost) to factory specs.
Where or from whom you purchase your gear is critical. I have found on line retailers Audio Advisor and Music Direct to be extremely helpful. That equipment quality issue I mentioned? Little/no help from the manufacturer but AA offered options, return, refund, trade etc.
I have bought from Moon Audio ….easy to reach and helpful. The owner patiently suffered my dumb questions and led me through some issues.
Schroeder Amplification a high end retailer were extremely helpful and easy to deal with.
I firmly believe it is the folks who actually sell you equipment that count. More than manufacturers. As a rule of course.
