No not at all.
That there such a a brand called Mcintosh is news to me.
I did not even hear a Beomaster 8000 untill I got mine home from Dillen the second time. It was in horrible condition electronic wise so the pick up day went like this: travel to seller, get it, back to the train station with it and then to Dillen after that 4 hours home.
Nearly the same with Beomaster 6000 but the palisander one (first one) has at least being able to play fine at lower volume and stable too.
I use only tube amps for my electric guitars and are critical enough. As it is I've been stuck with same 2 amp setups for some years and it feels like yesterday in most cases when I was trying it out. The same with my Beomaster 8000. It makes HIFI obsolete and non interesting for me.
A well serviced Beomaster 8000 and BM6000 too (Quite underrated here on Beoworld) will always have a good value. You don't loose anything by trying it for a while. Most likely you can get your money back if you don't want it.
