Jolida FX10 4/8ohm posts?

Hi, Klipsch forum!

 

I'm still looking for the right way to get into tube sound. Now that I have my pair of KP-201s, the time doesn't seem better to start evaluating what's out there, and word on the Jolida FX10 seems quite positive.

 

One thing I do notice is that it has binding posts for both 8-ohm and 4-ohm speakers. What do you think the difference would be under the hood? My limited knowledge of how amplifiers work tell me that the 4ohm posts probably produce quashed voltage (I think?) to keep it from being overloaded. Thanks to Klipsch Professional publishing all the relevant specs, I know the KP-201s have a minimum impedance of 4.5ohms. Which posts would I want to use if I got that amp?

 

One nice thing about the FX10 is that, being made to be an entry level tube amp, it is self-biasing. That's great, because I'm still not sure I understand bias. In a world where I found an entry-level tube amp that wasn't self-biasing, what would I have to know?  Would a new set of tubes typically say on the package how it should be set?

 

Thanks!

There may be subtle sonic differences between the 2 taps, so use whichever you prefer.  Unless you are constantly pushing the amp to its maximum output power, it won't hurt anything. 

 

Bias is only one of a number of tube operating parameters, is different for every amp, and cannot be understood in isolation.  I suggest that you check out the numerous online tutorials on how tubes work and then expand as your knowledge base increases.
