It was suggested to me that a tube amp (not preamp) is not recommended to play all day long, which is usually what I do. Do you have a different opinion?
Do you want music? Or do you want an appliance? The sound I am talking about you cannot get from silicon. Only tubes. Yes tubes do wear out and need to be replaced. Do you give up driving because tires wear out? If you leave it on all day then I assume it is background, or at any rate not that loud. With the speakers I’m recommending the amp will be doing some tiny fraction of a watt. Basically idle from the amps point of view. With that being the case your tubes will probably need replacement every two years, give or take, as opposed to going three to five the way I do, a couple hours a night, with an hour or so of that being fairly high volume.
Again, the speakers are the key. Get sucked into 90dB or lower like a lot of guys do and yes you will be pushing the amp hard. Easy to drive 95dB and up like Tekton the amp is hardly doing anything until the volume gets real loud.
People are funny. They love to make everything harder than it needs to be. Its not that hard. You get Tekton Moabs, Raven Blackhawk, then PM I will give you my phone number so you can call and gush about how you never even in your wildest dreams thought anything could ever sound this good. Take it to the bank. Cash the check. Spend the money.
