Looking at a Mcintosh 275vi with upgraded gold lion tubes

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.

Get some KR KT88s. Huge upgrade. Verdant Audio.  $$$ No affiliation.

I have Northern Electric, Gold lions, NOS Tungsol 6550 $$$$. I believe the original 275s which I owned in the 70s were voiced with the Tungsols. 

Thanks but I'm looking at a seller of two 275vi with upgraded gold lions I'm interested in one of them . Really looking for advice on whether to take a chance on someones upgrades and save 2k or just buy new and know what I'm buying

It's just a personal preference of how they sound. Both tubes are reliable and neither brand will sound bad,just slightly different from one another.After you've lived with the amp for a while I imagine you'll be trying other brands out of curiosity.

I believe the McIntosh MC275 MKV used Shuguang Penta KT88's... not JJ's.  I don't think the Gold Lion's are bad sounding in the MC275's I just preferred the crispness of the Shuguang Penta's (which I believe are no longer available).  I would not let the power tube be the decision maker as to whether or not you buy the amp, as I really did like the MC275 and in many respects I with I still had it.  It's well built, sounds great, dependable, easily serviced and has exceptional resale value.  I highly recommend it.  

What speakers would you pair it with?
