what impacts the sound quality more amp or pre-amp


which component has the greatest effect on sound quality, the amp or pre-amp? does one invest more in pre-amp to achieve sound quality?

It's hard to say. It really is all about components working well together. A relatively modest change in a system that contributes to better synergy can have a much greater effect than a more ambitious change that doesn't improve synergy.

One way you can be assured of a synergistic relationship between the preamp, interconnect and amplifier functions is to buy an integrated. Also, everything else being equal, you should expect better build quality and parts selection in a thousand dollar, single chassis integrated amplifier than a thousand dollar preamp, amp, interconnect combination.
I'm happy to stand corrected. Generally, I've been choosing efficient and easy to drive speakers to pair up with comparatively low power tube amplifiers. It didn't occur to me that Harbeths, for example, are relatively inefficient but remain easy to drive.

I realized that the numbers I was giving for efficiency and impedance were actually for the Alon IV. Having said that, I can't find Alon II measurements and specs. However, I did find this thread:

Where at least one person says these should be tube friendly.

Personally, I'd go with a tube integrated amp, or a tube power amp with a passive preamp. You still need to pick the right amplifier of course to get the sound you want as not all tube amps sound the same and there can be striking differences between them.
Pubul57 is correct about the 8 ohm nominal and 4 ohm minimum for the Model II. Here's a link to the Alon product manual. I don't know what year it was published, but it was during the production of the Phalanx and before the Circe. The Phalanx was one hell of an ugly speaker.
Hello, new here. Just a question about my choice of pre & power. I am currently testing the set up as I have an Onkyo M504 power amp with its matching pre P304, but, I also have a Rotel RSX1067 Surround processor. So with that said, I currently have the Rotel as my pre amp controlling the mains, through the Onkyo. Which are B&W CDM1nt bookshelf, speakers. Sound is fantastic. But more curious was the forementioned question. Is it pre or power. With this set up I chose the Rotel because of its superb sound quality. Any feed back would be helpful ThanksĀ
