Does the Transport make a significant difference

Ricred1,
the PWT has "very high" sound quality. As others here have pointed out, transports play a major role regarding the overall sound you get from CDs.

Hi RicRed, here are some questions for you...

* what sonic characteristics are missing, or you want to enhance, maximize, or simply modify, through the addition of a preamplifier?
*
In general, what are the most important audible parameters to you?
* What music do you mostly listen to?

Depending on your answers, we might come up with different preamp suggestions.

Guidocorona,

My priorities are spacing between instruments, imaging,and soundstaging. I want it all done with a neutral, natural sound. The Aerial 7T are very good accomplishing my priorities; therefore I want to maximize their capabilities.

When I added the PS Audio PWD II, my aforementioned priorities improved 30 or so percent. Music that I'm very familiar with had significantly more space and tonality to it. On one CD the lead guitar appeared in the middle, now it's outside the left speaker. My thought process is adding the PS Audio PWT should bring my system to the next level. Why the PWT? I already have the PWD II and it's in my price range.

I'm assuming changing preamps will take me to yet another level. The Parasound P5 performs many functions, but I just need a simple line stage. Why a preamp, because with my current configuration, with the preamp in, I find the music to be more detailed and natural sounding. I've heard significant differences between preamps, that's why I thought that should be the last step. My concern is finding something in the 2-3K range. I always set a range regarding what I'm willing to spend for a specific component.

I listen to Boney James, David Sandborn, Michael Franks, Joe Sample, Jesse J., Najee and many more contemporary Jazz artist.

"I'm assuming changing preamps will take me to yet another level"

It certainly can, but probably not for $2-3K. Good preamps start at ~$10K unfortunately. You might consider a passive transformer linestage. The Music First is very good at around $4.5K.

The fact that driving your DAC direct to amps does not sound better is probably due to either:

1) the DAC does not have low enough output impedance to drive amps
2) the preamp provides a level of isolation between the DAC and amps
3) the volume control technology in the DAC is inferior to the preamp

The likelihood is that the problem is #3.

The best possible of all worlds is to eliminate the preamp without using software volume control. Instead, use a volume technology in the DAC that does not add distortion or noise, such as this:

This volume technology is like no other DAC. There are actually no parts added for the volume and no analog circuits being adjusted. No bit decimation either.

The DAC is expensive, but replaces preamp, computer interface and DAC. All you need is a computer, amps and speakers. It recently won a multi-DAC shootout on Audiogon, beating out PWD, Directstream, Mietner MA, Lampizator, APL and others:

There may be a demo unit for sale soon BTW, at a discount.

Ricred, you seem to listen to music which has a combination of rapid leading edges that need to be handled without intermodulating the treble -- lest they become harsh, and lots of sostenuto in the melodic lines, which instead need mounds of harmonic exposure to sound emotionally involving.

The above, in combination for your need of a well defined three-dimensional space and images,, and a transparent sense of "natural", or '"organic" seems to spell once again the name of the Rowland Capri S2... It can be had with -- or without -- the DAC card.

Others on the thread will have other suggestions... Sonic descriptions in words can go only so far... In the end, you might need to try things out, and see what best fits your musical taste.
