+1 ARC CD9 / SE
Unless you actually purchase an extra transport from Audio Research's supposed stash of extra discontinued transports, I would find buying an expensive discontinued CD player without surety of repair a fools errand.
I find the theory that ARC discontinued this CD player because the manufacturer of the transport quit producing the the transport fishy as why didn't ARC just purchase enough supply of the transports before the manufacturer discontinued them to continue producing the CD player?
There is nothing fishy here. My dealer had a close relationship with owner at the time and heard about this straight from him. ( my friend is very savvy in manufacturing and has good EQ, so he was not being deceived.
Audio Research keeps a stock of parts to service discontinued products. Many very very old products can still be serviced. It is one of the many reasons to own ARC products.
I own a Ref CD9SE and have no worries at all. Also, had I not owned it when it was discontinued, I would have unhesitatingly bought one. Now, if it was made by a lessor company, I might hesitate.
You’re among many knowledgeable ARC lovers. But for me, and quoting myself, to calm all doubts of repairability other than hearsay, before I purchased the unit.
