Importance of Amplifier versus Preamp?

I like to have a great amplifier with a good preamplifier with same brand and generation.
The most important to remember that the goal is to increase your enjoyment of music. To me, I'm listening through a component that is going to make me happy, relaxing, and just settling into the music not the equipment.

IMHO, the preamp is more important, BUT the amplifier/speaker interface is more critical. Once you get the amp and speaker match correct, a fantastic preamp will make it even better.

My opinion is that a general purpose answer can't be defined. It depends on the specific components that are being considered, and also on how synergistically they match up with the speakers, the source components, and each other.

I would emphasize, though, that the amplifier/speaker matchup is one of the most important considerations.

Assuming your power amp has no trouble driving your speakers and it doesn't do anything really bad sonically, I would say that the preamp is easily more important. Just to give a rough example, if I had $5000 to spend on both pieces, at least $3000 would go to the preamp. Keep in mind, though, that this is very general info, and in audio, there are always some exceptions.

If you're on a limited budget and can't afford a really good active preamp, a passive unit is a great alternative. There's nothing worse than having to suffer with a cheap active line stage. Especially if you're new to high end. Chances are that you won't figure out what the problem is until after you spent a lot of money.

What Almarg said. Labels on components alone like "good" or "great" mean nothing. its only as good as the weakest link in the chain and each chain is different. Lots of ways to make really good chains. Start with getting a handle on teh speaker/room interaction including an amp well suited to drive the speakers. Then choose a pre-amp (if needed, not always anymore depending on what source gear will be used).

All these things alone will have a major effect on the sound. YOu have to get the whole puzzle right which means teh right pieces that match. At minimum, you need speakers, amp and one or more sources. Pre-amp these days is optionl. A passive pre-amp is another option that can work very well if done right. It all depends. Sorry, but if you really care about how things sound rather than just listening and being satisifed, this is what you are dealing with. Good news is if you like this stuff it may be a fun journey. Otherwise, not so much.
