Hi Tee, I'm still learning also lah... Hehe... Impedance matching is important... Try to get as close as possible. Most of the tube amp has 4 ohms, 8 ohms some even 16 ohms O/P, so that can match with difference impedance speaker. Tks... Share this post Link to post Share on other sites
tee 0 Report post Posted August 22, 2003 you mean matching impedance for the cans...not speakers. Share this post Link to post Share on other sites
dBu 0 Report post Posted August 22, 2003 you mean matching impedance for the cans...not speakers. Same theory lah... Especially tube amp using O/P transformer... So the sec. of the transformer (impedance) must match to either speakers or headphones... Share this post Link to post Share on other sites
