tubes and current


hi all, I current use a 300B SET with a pair of B&W805 D3 sounds good but with obviously drawback that the B&Ws love high current and the 300B SET can only do so much.  I've been saving up for a second tube amp for large orchestral music and when I want lush full body sound.

I've been looking between EL34/KT88 amps with 4 tubes vs 8 tubes.  I have borrowed a 4x EL34 tube amp before and there was more than enough volume for me, so I don't need 8x tubes for more volume.  What I'm wondering is if 8x tubes would produce 1.5x-2x the current produced or is that really just a design of the amplifier not directly related to number of tubes.

Otherwise, any high current tube amp you guys like below $2500 used or new?  
Is it worth trying 300B push pull or 845 SET?

Thanks.

You may end up with significantly different sound by switching between amps and tubes.  If you love your current sound and just need more power, you have answered your own question as to buy a second amp.  However, that may not be enough power for your needs either.  What 300B is your current amp?  That will get you better suggestions.
If you like the warm tube sound and love those speakers, consider a Class A amp.  You might find an Aragon, Sumo or other for a reasonable price.  Pass Labs will do what you need but are not cheap.  Otherwise you need a big tube amp such as Cary v12.
There are fairly efficient speakers out there that aren't as unique as single driver speakers if you can find them.  Coincident is my favorite but you will find others rated at 92db or better.  92db will barely cut it with 8 watts.
