Accuphase is an interesting company which produces high quality components in small batches by hand to very high standards.  They have limited their size and production volumes to 5,000 units and only have about 85 employees - 26 of whom are engineers.  They are primarily focused on the Japanese market and only about 30% of their units are destined for export.

According to the Management and Corporate Policy posted on the Accuphase website, they limit production to 5,000 units per year and are not looking to expand:

"One of the corporate principles that Accuphase has observed since its
beginning is the conscious decision not to pursue expansion. In a free economy,
most companies try to grow. However, demand is not unlimited. If we were to
chase the numbers, trying to sell more and more products and compete only on
price, we would lose our ability to create truly high-end audio components.
We therefore are not increasing our staff numbers (currently about 80, similar
to the time of the company's founding), in keeping with the principle of "small
numbers ‒ exceptional talent". Rather than trying to expand the scale of the
company, we believe in quality over quantity. We adhere to a low-volume
production schedule, building and marketing only about 5,000 units per year. But
with regard to the products that we are making, we passionately care about their
sound, their performance, their quality, and their design. We do not ship a
product unless it fully meets our exacting standards. This gives it lasting value
and ensures the excellent reputation of the Accuphase brand."

Those Michi sure are VERY powerful....but I am leaning more toward the Accuphase brand.

toronto416: Nice company! I like their approach to business...no shareholders....no hurry.

Pass Lab products have the reputation for being built to be extremely reliable. This reputation is based not on verbiage from their website, but rather by very rarely having a problem in peoples system.
They are typically very conservative in rated wattage and have huge power supplies that will happily drive most anything. They have a sound type, driven by listening tests more than specs.  They are slow to break in, so any audition of a PL amp should allow more than 100 hours before forming an opinion.
Good luck in your search!

I use an Accuphase A-36 power amp and Accuphase C-2450 preamp along with Fritz Carrera speakers and an Aurender A20. The sound is sublime. I owned a Pass Labs XA25, Boulder 866, Ayer VX-5 Twenty, Luxman 509z, and a few others and all are great amplifiers. However, I cannot recommend any over the A-48 you mention. The only reason I didn't go with something bigger than the A-36 is because my speakers do not require more power to achieve the great sound those Fritz speakers are capable of producing. I also use the A-36 with Klipsch Chorus IIs. Perhaps not a popular choice for many but I love their house sound and I also use a 10wpc Luxman tube amp that has a synergy with those speakers like no others I owned or heard. The ONLY other recommendation I have is get a matching Accuphase preamp. I have tried other premps, both SS and tube but the Accuphase preamps produce the best sound for me.
