Prefered 300B tubes for Canary Amplifiers


I'm the owner of a Canary 306 300B amplifier. The stock tubes are EH and I'm interested in upgrading to a premium set of 300B tubes. I'm wondering what others have tried and liked and wondered whether the Canarys can accept the XLS designated tubes.

Cost, he is letting you know that these are very reasonably priced for good 300b tubes. Higher end 300bs  can easily cost 800 to 2000.00 dollars per pair. For example I have Japanese Takatsuki (1800.00) bought about 5 years ago and Czech Republic EML XLS (850.00). Of course  vintage Western Electric 300bs can go for much more.

Phaelon makes good sense, with 4 tubes the cost begins to matter.I use the Takatsuki as gary mention above and it is brilliant. The Sophia Royal Princess is excellent in my SET amplifier and better than the WE 300b reissue tubes I tried.The Sophia RP are a lot less than the Takatsuki. I would definitely consider the EML tubes, they have very good word of mouth reputation.
Regrds,
My amplifier's stock tube was the EH Golden Grid and it is a solid 300b.It in

no way compares to the better tubes mentioned here, not even close.
Stupid money is obviously a personal opinion. The Canary is hardly an
inexpensive amplifier, why not consider a premium tube to get the most
from a worthy design.The 300b have a pretty long life span (my SET is very
easy on these tubes, 25 watt dissipation).It's an individual choice, in my
case there's zero regret. The Takatsuki is indeed worth every cent for the
stunning sound quality it provides. It is truly one of the best audio
purchases I've made.Others are certainly free to agree or disagree. I bet
there're very few who have actually used one of these superb 300b tubes
and and wouldn't do it again in a heartbeat. Sure driver tubes make a
difference but the better 300b tubes can improve your sound very
significantly. To each their own.The Takatsuki, Sophia RP and I'm sure the
EML can honestly transform the performance of a well made 300b .Every
single time I use my amplifier (which quite frequent and for long sessions) I
am rewarded with the sheer beauty and natural presentation the premium
tube yields, how do you put a price on that? That's the entire point of
owning a good 300b amp in the first place.I want the most it has to offer,
well it sure delivers without fail(an understatement).

Gsm18439 (gary) makes a good point, I 'm unaware of any review or user feedback with PP amplifiers. Any tube can potentially hit or miss with a given amplifier and certainly some will mate better than others. The WE 300b is praised by many but in my own amplifier it was outclassed by the Takatsuki and Sophia RP, they were on a much higher plane(I know people will have varying outcomes). The true value of a product should be determined by the level of results it provides. The better quality 300b will simply allow a superior listening experience and deeper involvement emotionally with the music you love, what more could one ask of their audio system? As gary mentioned,I also got mine a year ago direct from Japan for 1400.00, those days are gone.Would I spent 2000.00 when I need to replace my current b pair? Absolutely! They have been extraordinary at connecting me to the soul and core of the music I enjoy.

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.

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.

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.
Regrds,
The original WE specs predicted 40K hours as Brf said.Certainly that figure
will vary based on the brand and quality level of current tubes and how hard
that tube is stressed in a given amplifier. The Takatsuki is reportedly
constructed to a very high tolerance level (strict adherence to original 300b
specifications) with premium materials, only time will tell.When I got my
amp I asked the builder Israel Blume how long would the tubes last.He
replied that the amp is very conservative and easy on the 300b and they will
last for years(only 25 watt dissipation).Gary do you happen to know the
watt dissipation for your amplifier? The lower the number generally the less
stress on the tube.Maybe SET circuits are easier on the tubes, I really don't
know.

I know, 40K hours is hard to grasp.As Brf pointed out however this tube was designed for very long and trouble free use fot telephone line service. This was meant to be from the outset an ultra low maintenance service tube. What is critical is how meticulously the various current 300b tubes are made.Suppositly this is a design objective by the Japanese engineers assigned to the Takatsuki project.The tubes are too recently developed to know yet their longevity. I can only attest to superior sound at this stage.

What you wrote makes intuitive sense, push pull use shouldn't be any more stressful as the duties of the output tubes are shared.We need a amp builder to comment.
