Looking at a Mcintosh 275vi with upgraded gold lion tubes


Do these upgraded tubes sound better then the original tubes? Do they have the same life expectancy.? Or is that an individual preference, or just  steer clear, and look for  275s with Mac. tubes? Welcome your advice .

I'm a big fan of Gold Lion KT88's, preferring them over others in most KT88 amps that I've owned, with the only exception a McIntosh MC275 MKV... for whatever reason I preferred the stock McIntosh KT88's over the Gold Lions, which surprised me at the time, given my preference towards Gold Lion.

Mac uses JJ tesla's in their tube gear so the gold lions will be a big upgrade IMO.

the JJ's are rather bright, toneless, and rather unmusical. they are like modern SS amps IMO.

I've changed all the stock tubes in mine with NOS tubes. but the Gold lions are great modern tubes i have used them in various other tube amps and preamps over the years.

All I'm going to say is the stock JJ's are not the best sounding tubes on the market but descent i suppose for modern tube that are not too expensive, they are reliable though. 

Thanks for the feedback. So far one pro and one loves gold lions but didn't love them in the 275v. I would be using a stock MC70 tube preamp. With all the tube swapping out there I thought there would be more of a response  to this thread.
