Different tubes different flavor

Hello everyone. I am sure this topic is widely understood by the experts here, but I would like a general overview of different opinions on different tube amplifier designs.

I currently live in China, a land full of tube amplifiers hard to find info on. Right now I have an Onix SP3 and a small hybrid amplifier used to power a pair of small, high sensitivity speakers.

I am intrigued by the offerings of Yarland and am trying to decide between these tube amps to find a change in sound, which both cost around $200 USD here:

1. http://www.yarland.com/en/product_13.asp

EL84 wired in triode I believe.

2. http://www.yarland.com/en/product_14.asp

Single ended, 　Power Tube: EL34B or KT88 x 2

　Impulse Tube: 6N3 x 2

Any input on the different flavor these might offer?

Thanks!
