A deeper more holographic soundstage.

If you want depth, this setup will give you audible depth.

I also forgot to say that you should look for a Dynaco QD-1 quadapter. They are rare, but not THAT rare. Use Google and one should pop up. If not, contact me. I have an extra one, although I really don't want to give it up.

I don't know what kind of music you are into. However, Radiohead - King of Limbs is a live studio recording. It has some of the best ambience I've ever heard recorded. On an ambient loop system, it is incredible. 

I forgot to mention that it is on DVD.

A lot of good responses already, and many not so good.

In my 45 years as an active audio enthusiast, the biggest single improvement I ever got in soundstage openness, depth and clarity came from having an electrician install two direct runs from our home's breaker box to audio-grade sockets in my listening room. I have spent many thousands of dollars over the years without getting so dramatic an improvement. Cost in my house was $1,200, which is higher than most because it required a complicated run.

Close second was from upgrading the power cords on my equipment. A lot of flat-earthers think this is nuts, but the improvements are NOT subtle. If you're using stock cords and don't have much to spend -- or want proof before spending more -- I strongly recommend Audience's cheapest cord, the F3 at $149.

Compared to stock cords, you will not believe the improvement -- even in relatively humble systems. I got a non-audiophile buddy to buy one for his Sprout100 integrated amp, powering a $300 pair of Elac Debut B2 6.2 speakers, and he said it gave him at least 20% more depth, clarity and dimensionality, revealing much more of what was in the recordings.

And, BTW, an F3 absolutely killed a Pangea AC-14XL, same price.

I use higher-grade Audience cords in my main system, and the Front Row -- very pricy -- is so good I can't believe it. Can hear to the walls of the recording venues, hear the air around and behind the players/singers, much more 3D and much clearer, more focused bass.

This is NOT snake oil.
