Importance of Amplifier versus Preamp?

My experience suggest source and preamp is where I hear the most significant differences. I submit the preamp is the hardest component to get right...at least that's what I'm going through at the moment.

Using the same manufacturer doesn't guarantee anything. I have a Parasound A21 and recently purchased a Parasound JC2 preamp. I thought that would end my quest, but I hated it. Going direct from my PS Audio Directstream was better to my ears, but something is still missing. My quest for the right preamp continues!

Rockenroller, where are you? You have initiated a good thread and have received much great advise and not responded with additional info in specifically helping you. Again what speakers and budget?

Thank you all of you Gentlemen and Ladies for the insight.
I feel like I am learning a lot about this magical world!
Here is my equipment:
amp: SAE 2401, vintage
preamp: Nikko Beta 2 , vintage
Sony TA77ESD, vintage
Yamaha CD300S cd player new.
cables from Blue Jean cables.
I listen to classic rock, blues, some classic.
as far as budget , I am looking at maybe another 1500.
All advice is much appreciated.

I generally agree with Syntax; great pre-amp and very good amp if a compromise has to be be made. In this case, however, I think an integrated really makes sense. There are some very nice tube and solid state choices listed here right now in the $1K-$1.5K range if you want to buy used (or new, the Wyrd4sound mINT integrated w dac and headphone amp is a new piece). Your speaker choice is very important in terms of going to tube vs. solid state amplification. Generally "speaking", speakers with lower sensitivity (listed in specs as dB/watt/meter or foot), those spec'd as nominally lower impedance (4 ohms or less) or with large variations in impedance with frequency, are better suited for solid state amps. Conversely, higher sensitiviy, higher impedance, more constant impedance curves are well suited for tube amps. Since you like rock and blues, I'm thinking that if you went tube, an "ultra-linear", tetrode or pentode circuit type would be more to your liking. They make more power with the same tubes and are often described as having more "drive" than triode circuits. For a variety of reasons, most people feel that tube "watts" are more powerful than solid state "watts". Of course, from an electrical standpoint, watts is watts, but to many people's ears, a 50 wpc tube amp would sound as powerful as a 100 wpc (or more) solid state.

Of course you want the amp and preamp to be faithful to the source but after using several preamps with my amp (McCormack DNA 125) I realized one thing quickly....that the amp was not the bottleneck. In fact that amp went through several upgrade phases and I felt no need to change it out. I used three different preamps and three different pairs of speakers during the time I had it. I have since replaced it with a pair of Quicksilver mono amps. Are they better ? In some ways yes, but that DNA 125 was a great amp.
