While speaker sensitivity is important when considering tube amp matching, you should place as much weight, if not more, on impedance (how easy the speaker is to drive). One reason Joseph Audio Perspectives (eg) work so well with many tube amps is because they're 8 ohm speakers that never dip below 5.5 ohms. Yet their sensitivity is only around 84dB. Tube amps 50w and higher should work well with them.
Never Owned a Tube Amp and Want Advice
Hi All,
I have never owned a tube amplifier before and am planning to purchase one with a minimum of 50 watts per channel to mate with 8 ohm 88 dbl speakers.
My hope is experienced audiogoners will share their expertise regarding how to approach this. While I realize listening is the best way to learn about sound and compatibility; I want to learn a better understanding about brands with less maintenance and longer tube life, how to decide between mono or stereo,can a newbie play with bias or is auto biasing a better first choice, etc.
I would also appreciate what to look for in selecting a used tube amp to identify one that might be in need of repair. For example, with solid state depending on the brand, capacitor replacement can be more of a concern. Any advice on what to look out for or ask about with used tube amps would be appreciated.
A big question I have is how to understand the relationship between power tubes like E34's, 120.s, etc. and, I guess the driver? tubes like 12au7's and 12at7's. That is to ask which is more critical to the overall sound of the amp? FWIW, I routinely tube roll with my preamps.
I 've read through a number of threads but maybe someone can point me to good ones I may have missed.
Thanks for listening,
Dsper
