Preamp or Amp?

I started a thread that has gotten no responses so I've started another one. Hopefully this is much more direct. I have a simaudio intergrated amp. Would I hear a difference moving up from an i-3 to a higher i-5 or Classe' 151 OR would I be best to move my budget up slightly and begin the trek down the seperates road.

Does the Preamp effect the overall presentation of a system more then the amp? I will be using Polk Audio LSi15 speakers. At what level of separates will I hear a significant improvement in sound quality? I've been doing some light reading, and have read up on some preamps the Copland 305, some CJ units...regardless of what I buy down the road, it will be used. Can a Jeff Rowland concentra or SimAudio i5 really keep up with most separates? I've been told by a few people they can. I'm not sure if it matters but the source is a John Wright modiffed Museatex DAC/transport combo.

I like the idea of simple one box solutions, not to mention the money saved on wiring. But a few people on this forum have told me if I like the sonic signiture of the LSi speakers, perhaps maybe it's time to look at getting a dedicated amp/pre-amp for further improvements, if thats the case which should I get first, the amp or preamp?

Preamp over power amp. I am not that familiar with your equipment. However, as a rule of thumb... A Preamp upgrade, whether it is a stand alone component or within a higher quality integrated, is the fastest way to the pot at the end of the rainbow (At least in my experience).

The right preamp CAN make an astonishing improvement . To comment on a reference to Totem speakers above , i have found every model the company makes to be smooth and grain free . There is not a dud in the entire line .

In my extensive personal experience, the PREAMP makes the biggest difference sonically.
They all sound vastly different, and they can make or break a system.
I have had more frustation over the right preamp than any other components in my system, by far!
Power amps can also make or break a system, but not to the degree that a preamp can in my own personal experience.
The only other component that can make as big, or bigger, sonic improvement than a preamp, IMHO, are the loudspeakers.
Just my 2 cents.

I'm going to make a suggestion that might be so obvious that I'll get hooted off the board. If your current integrated has a capability to separate the pre and power sections, perhaps you could work with a dealer and get some pre's and amps that fit your budget to demo. Try a pre using the inputs to the power amp section and then compare the sound to using the pre-outs from your integrated with a better power amp. The comparative results might tell you where your money could best be spent. Then you can stagger upgrade purchases appropriately to get biggest sonic bang for your budget.

Brainwater: I've heard many great things about the Totem lineup. I've heard the Mani2's powered by Simaudio Celeste and wasn't impressed at all, even the owner of the Totems prefered the LSi's to his older Mani2's. Perhaps it was the mix, but I found the presentation to be stale, the LSi's really bring you in. I can listen for hours.

I've always been a source first guy, hence the reason I've spent so much (or little depending on how you look at it) on my redbook player, to ensure everything upstream would benefit. I really don't know what kinda level of preamp amp I would have to get in order to best a top flight intergrated like the Simaudio i-5 or Classe' cap 151 any suggestions?
