Valve amplifiers

Superted,
You have to trust what you hear and your spontaneous reactions. No surprise that you'd be very much attracted to a good SET amplifier. They make beautiful and natural sounding music (isn't that what you want?). My SET is ultra simple to maintain and utterly reliable. With appropriate speakers all music genres can be enjoyed.
Best of Luck,
Charles,

When it comes down toe getting it Charles1dad, you are absolutely correct. It's the sound that counts!! I was just a little wary of reliability issues as I seem to be getting mixed messages.

Also, I was trying to get some heads up on the machine I have been listening to - the Mastersound Compact 845. It's the only one that I have heard. Are there any other machines that would get a recommendation and are worthy of a listen?

Many thanks to you.

Superted,
I haven't heard the Mastersound 845 amplifier but it's has a good word of mouth reputation. There are numerous highly regarded 845 SET amplifiers available. They cover a fairly broad price range. Try to make an effort to hear others and get familiar with their varying sound characteristics. Key question is what speaker would you mate to them? This is a fundamental point with SET amplifiers. Take some time to read and learn more about these types of special amplifiers. You obviously have good ears.
Charles,

The world of tube amplifiers is vast. There are certainly many other amps that are worthy of a listen!

Much depends on your loudspeakers. What kind are they? What is their impedance? How efficient are they? How large is your room? How lively is it? These are some questions that if properly answered, will help you a lot.

For example, if your speakers are 8 ohms and 91 db, and your room is average size, you will want to look at more powerful amps. That might mean something push-pull rather than SET. SETs are best used with speakers that are more efficient, such that they are never asked for more than about 20-25% of full power. If you obey this rule, you will get the best investment dollar out of an SET.

So answering the speaker issue is a must. You might also want to take a look at this link:

The world of tube amplifiers is vast, no argument on that point. Superted was captivated by the sound of the 845 SET amp he heard and I understand this and thus stayed on subject. I'd encourage people to listen to all types of amplifiers and expand their knowledge and experience base. When all is said and done Superted may still gravitate towards the SET beauty he recently heard.
