Tubes for Canary 330 mkII mono's


I purchased a new pair of Canary 330 MKII's yesterday, I should get delivery next week.
The amps ship without 300b's but ship with 6sn7gtb's and 5u4gb's.
I have 2 pairs of KR 300b bxls , test tube shape and not the new s shaped that I plan on using .
Can anyone comment on how the KR's will sound ?
The dealer recommended EH 300b's gold pins.
I would also like recommendations for 6sn7gtb's and 5u4gb's .
I have Coincident Total Victory IV Loudspeakers and any comments or suggestions are appreciated.

Thank you,
Abill

Thank you Peter and Mechans for the response.

Mechans,
Are you using Canary amps ?
I don't know what you mean by "coin base " ?
Do you mean a metal base ?

I'll listen to the amps for 50 hrs and then post any questions.
I like being closer to the stage, if the auditorium has 20 rows , I would like to be in row 5-6 with good seperation .

There is a post at Arthur Salvatore's wedsite about someone using Canary 339's with EH 300b's and 1960 Mullard CV 378 rectifiers and 1952 Sylvania 6SN7WGT .
And the sound is breathtaking .
I need two pairs of each type of tubes so I want to be careful getting the correct tubes. I know tubes can get expensive very fast.

Regards,

Abill
No I am not using Canary's, that's why I was cautioning you about the GTB vs the GT's and GTA's. If Authur Salvatore can use WGTs then you can use almost any type you want.
Coin base is a thin black plastic base found on recent/late 70's GTBs. It resembles a poker chip or about the thickness of a coin.
The concert hall sound stage you want may be found if you use the Sylvania GTs. I would guess that you'll end up with W's after doing some experimenting or"rolling" which is the only way to know if you have nailed the sonic you want. If you want to try the WGTs (which have T shaped opposing 3 hole black plates architecture and a brown base with green lettering) be careful not to buy the WGTA which is generally thought to be somewhat inferior. They have very good imaging, are very detailed and are fast.
