Whats the FATTEST sounding Tube amp to warm up Lean speakers?

@xti16 Nothing wrong with sharing your impressions! Lots of nice 6550/KT88 tubes (new and old) types to chose from - I hear some of the new production (reproduction?) stuff being made today is quite good.:-)

With the 6C33 all we got are those tubes mostly made in the Soviet era by a few different facilities in Russia... fortunately its a pretty good souding tube (IMO) in general, so the best bet for tube rolling in a Joule amp are the front end tubes (6922, 5751, 6350)

I just rolled out some well matured Brimar 6L6GCs and put in some lightly used Valve Art KT66s.
The Brimars sound raunchier but a little lean.
The Valve Arts have a much better bottom end but sound airier as well. These will be staying put for quite some time I'd say.
Hope this helped.

If you must keep the speaker then try Cary 805 or Jadis!

I owned the Merlins at one time. They sounded very good with Quicksilver Audio M80 el-34 tube amps.

I agree on #4, no power conditioners.

They cannot fix a difficiency in an amplifier's design. The resistance of the series chokes adds to the resistances in the primary circuit. They add yet another power cord and socket,more resistance. Here we are trying to lower the resistance in the primary and then go and add perhaps more than we have subtracted.

Do any power conditioners give their effective series resistance?

@ramtubesNot all power conditioners are the same!! However most offered to high end audio seem to be so much junk. There are some that have no series chokes at all, but still are able to provide a pure sine wave at full power, which can be quite a lot.

You might want to take a look at some of the Elgar power conditioners like the 3006 series and you will see what I mean.
