While NO company has 100% great products, yet over the years (1970-2022) they have been in business, ARC has had more "wins" than most companies have had ever.
Interesting to see that their first break-through pre-amp from mid-1970’s (SP-3A1) STILL commands huge prices. I sold it when it went from $595 to $695 to $795 and could never keep them in stock. Today, on ebay, etc., they go for over $3000 and they are over 45 years old!!
Another flagship back then, the two-chassis SP-10, is still considered one of the best ever! Their new stuff is also wonderful if you can afford it.
BUT, you have to listen IN YOUR ROOM to whatever you pick and make sure it fits YOUR system. Personally, I would buy ARC EVERY TIME, but you need to know a couple of things:
1. They had some duds with their solid state stuff
2. There are some items they can no longer service. You should call them and see before you make a final decision. Their service is legendary, if expensive, but as in most things in life, you tend to get what you pay for.
Best of luck to you, and should you go with ARC electronics, have your dealer hook up a pair of Magneplaner speakers in your room and see how that combo grabs you.
Cheers!
