5AR4/GZ34 Rectifier Tubes

Geoffkait,

Sound wise, they are both very similar but the Bad Boys doesn't have the bloom and extract more details from guitar pics/slaps; they're just more transparent in pulling out the slightest amount of ambiance and details from the recording...

The VT 231 may be a little smoother due to the bloom they project but It's a matter of preference for sure.

Just put my new golden lion genalex in my Modwright power supply. Right out of the box there was an improvement in the base depth. I am using the Sophia's for the Sony ES5400 player and have been toying with the idea of some 40's NOS Sylvania's. Has anyone moved on from the Sophia's?

Goose, I think these Gold Lions are going to be hard to beat based on my experience so far. PSVane claims they have a 6SN7 equivalent that people really like in ModWright gear. One of the ModWright website photos shows an Oppo with the PSVanes. You might give Dan Wright a shout and see what he has to say about them.

Brownsfan I am actually surprised how good the gold lions are. Perhaps there is hope for new stock product. I will need to check out the PSVanes. Thanks for the tip.

Goose,

I had the Sophia's in my system for about a month before I started experimenting with NOS tubes; Sylvania Chrome Dome walked all over the Sophia's but they sold rather quickly.

Also tried the Psvane, too dark for my taste...
