Have a close look and listen at the Tron 300B Jubilate (www.tron-electric.com) distributed in the US by Highwater Sound. Tron is a tiny UK based manufacturer; the amps are designed and made by Graham Tricker, who is rated as one of the world's best valve amp designers. All his amps are made to order by him and no-one else. I have his Tron Meteor preamp (new model is the Syren, which has had rave reviews) , which is Very Very good. I'm looking to buy some 300Bs as well. Just beware that many 'new' PX25 amps use 'new' PX25 valves, which are more like modern 300Bs than the original M-O PX25 valves. More importantly many modern PX25 amps have modern valve bases and will not accept NOS M-O PX25 valves, which sound stunning.

Hi Linkoping,

It's great to hear you've already used a Jota because it is very hard to describe how AA amps.

You might want to talk to Joe about their high powered Jota which uses the KR52BX tube. It puts out 40-50% more current than the Jota you used. That might be enough to handle big orchestral works that you like.

If not, you can always have Joe make you Jota 300B monoblocks.

After that, I don't think there are many other 300B amps under $10k that have greater drive. No wonder you have that parallel 845 amp!

I suppose you are considering bi-amping with the PX-25 for mids/highs and your Matersound 845 on the woofers?

Hey Linkoping,

Have you considered going after the Art Audio Adagio monoblocks being auctioned here right now?

The Adagio are the most powerful amps AA makes. Depending on the output tubes used, they are 40 or 60 wpc. The bass output is supposed to be stunning. Don't know aboutt he rest of the audio spectrum.

They are currently at $7,400 with 2 days left. Maybe you could lucky and get them for $10k, though biamping with a PX-25 on mids/highs and your 845's on bass is probably the best of all worlds.
