Slightly less warm/better definition(realism), but- still with an extended life expectancy(20K to 30K hours). There are also a few differing iterations, within their metal base, GZ34s, that will vary slightly in presentation. I prefer the tall bottle, 5R4GYS. You may find a change from the Blackburn Mullard, a sideways move. I’d never dissuade one, from experimenting, though. It’s all about ones own aural palate and system, in their listening room.

Personally; there are only two 5AR4 iterations, that I would consider against the Mullard(Blackburn) GZ34. Both, from Philips: https://www.ebay.com/c/168100339 and: https://tubeworld.com/gz34metal.htm No connection to either reference. |
