Tube rolling Question

Hello Tube Rollers
I recently bought my first tube preamp (Blue Circle 21.1). I've noticed I am need of new tubes as the tube whoosh is considerably more noticeable now than 6 months ago. The amp comes with  Electro-Harmonix 6sn7 tubes which I appreciate and dig the sound. I will certainly replace these with a the gold pin model as I like the sound profile. Here's my question:

What other tubes might you recommend for a different "flavor" of sound, and just to have fun with. I am a poor audio guy so please no recommendations for tubes that will cost more than preamp. 

Thanks in advance.

Electro-Harmonix 6sn7 sounds too bright.

I recommend you to look for Ebay dealer on NOS Silvania vt231 who offer return like this.

One recommendable choice of new production tube is
Shuguang Treasure CV181-Z .

It sounds sweet and balanced while NOS Silvania vt231 sounds more dynamic and detailed.

They are compatible with 6sn7.
