Sorry for such a basic question.
How do I go about connecting a Yung plate amp to either my tube amp. Which is just your basic kt88 with one input and 4 and 8ohm speaker outs.
My pre is the decware csp2
Audiophile Tube Preamplifier / OTL Headphone amp by DECWARE

Which should I connect to and what would be the best way to do it.
I'm waiting to order the amp(s) so I get the right connectors too.

I will be getting either 1 or 2 yung sd300. Also not sure if I should get boost or no boost. I'm thinking I should get boost since I'm doing open baffle.

Thanks so much for your help.

I suggest you try the speaker level I/Ps. That way, you have a fighting chance for the S/W to pick up some of the tube amp's sonic signature.

"Super duper", fancy, speaker wire is not needed to connect the S/W to the tube amp, as it should present a high impedance and it also responds only to bass. 16 AWG rope lay, OFC, zip cord is plenty good here.

Adjust the controls of the S/W to obtain the best sound. The main speakers play as close to full range, as they can. The S/W is used to fill in underneath, were the main speakers can't go.

Better a little less than ideal, rather than too much.
