KT88 Tube Recommendation - Mac MC275

My parents have a gen 5 or 6 Mac MC275 (new ~ 2018). Preamp = Mac C2600. Speakers = Klipschorns.  Music - mostly lossless streaming with very eclectic listening ( Yes/Pink Floyd to Musicals, Johnny Mathis, Stevie Ray Vaughn, etc..) 

They replaced the pre-amplification tubes in the Mc275 a couple years back with Gold Lions. I'm looking for recommendation on a matched quad of KT88, as the ones they are running probably have > 2000 hours and to me are starting to sound less defined and articulate when I visit.

Budget ~ 400 bucks would be nice to stay at. I am sure a lot of you have an MC275, and would love to hear your thoughts about replacement KT88 power tubes.

If its a gen 6 they have JJ tubes from the factory, not the best sounding tube IMO. Lots of options, maybe not at your budget though. Tube store has Gnelax kt88's for a decent price right now.

You can also run 6550's if your inclined. with K-horn's i would definitely try 6550's. not much new production for the 6550's though.
