Prefered 300B tubes for Canary Amplifiers

Bnrlaw,
I don't believe anyone responding here is defensive, why should we be?
This is a open forum with different points of view expressed.Your approach
is a valid and reasonable one, particularly when dealing with multiple pairs
of 300bs to replace (your case 4 pairs).You used the term "stupid
money" others here are giving an alternative perspective, nothing
more or less.This is all relative, some would contend we all spent stupid
money for our amplifiers in the first place (wasting all that money on tube
amps when many SS amps are available for far less money and more
watts!).If I needed 4 pair of 300b tubes, well then the Takatsuki is perhaps
out of range, obviously a personal call.I think we all can come here and
exchange opinions and not be considered defensive for presenting our own
experiences. No one else responding has used a derogatory term "stupid
money" other than you.I think the rest of us are relaxed and just enjoying
this thread.
Regards,

You did however take offense at the phrase "stupid money"
I meant nothing by it.
Anyone who posts here can be accused of spending "stupid money" if they spent anything more than a couple of hundred dollars on a stereo, when taken from the standpoint of a non-audiophile. It is all relative. Obviously, almost none of these purchases are stupid to us if we hear a change and derive enjoyment from it. My point was....I am with you. We are on the same page, though I didn't get the impression that you thought we were.
No worries.
Have fun.

Bnrlaw,
I'm with you, ,sometimes the true meaning of what we're trying to say gets lost with written text.In person and talking face to face this wouldn't be a problem. I just assume most of us who have 300b amps are the types who really connect emotionally with their music and enjoy discussing this with other liked minded people.
Charles,

The price of new production 300B tubes has really escaladed over the last couple of years. I remember when a top China 300B could be has for $200/pair. European 300B, EAT, AVVT, EML, KR Audio have always been around the $700/pr mark. China and now Japan has seen a great appetite for premium 300B tubes and have marketed these tubes primarily to the US marketplace.

I am not going to comment on the value proposition of these new production tubes because price performance is purely subjective. I have listened to Takatsuki and they are indeed a superb tube, but at a price of $2,000/pr, they now make some of the European 300B look like a bargain.

On the plus side, 300B’s last a very longtime; therefore, the sting of price can be offset with the number of years of enjoyment you will get.

Also, from what I have read, 300B in PP configuration run the tubes harder when compared to single ended, therefore, an XLS tube may be better suited for your application. Take a look at the Canary specs to see exactly how the tubes are stressed. Take your time, and see what other Canary owners are using.

I know that before Coincident started marketing their own amplifiers, Coincident used Canary amps with KR 300B.

Brf,
One great feature of 300b and low power DHT tubes in general is their longevity, much better and also more reliable than my prior KT 88 and 6550 tubed amps(won't go back to that).Unless you have an amp that really pushes the tube, most should get many enjoyable years from their 300b.What is the operating point and watt dissipation of the Carnary circuit. Maximum dissipation for the 300b per WE standard is 40 watts.It would seem a push pull circuit should be easier on the tube since the driving is shared among the tubes (one pushes and the other pulls)as opposed to the SET where the tube responsible for the full cycle.I certainly could be wrong.
