Where should I concentrate my upgrade dollars next


I'll dive right in & pick your brains. In your opinion, what should I concentrate on upgrading next in this small setup? It's in a cottage with a view and I'd like to keep the view central and gear clean.
I'm running:

SlimDevices Squeezebox 3
Rotel RCD-1070 cd player
Channel Islands Audio VDA2 with upgraded outboard VAC1 Power Supply
Jolida 102B tube amp
Omega 3 Grande full range speakers.

Cables:
From SB3 to DAC = Zu OxyFuel Digital Coax
From Rotel to DAC = Zu OxyFuel
From DAC to Amp = Zu Wylde RCA
From Amp to Speakers = Straight Wire Waveguide 3

I have a Monster HTS 5100 other power conditioner tuned for digital and analog depending on the plug.
Plus a B.I.C. turntable and Parasound phonostage pre, but I'm not interested in upgrading this portion.

+90% of my listening is via the SB3 / CI DAC streamed in ALAC from a PowerMac server. The musical tastes run all across the board: Vivaldi with a sunset or snowstorm and Haydn while cooking. Stills with a beer. Ska on ski weekends... etc.

The soundstage is definitely present and the setup impressed party guests this past weekend. Simple clean looks and it's okay enough to pick out individual instruments and vocals and pinpoint there location on stage, but it's just not doing it for me anymore.

It's not a high power system, but that's not what I'm going for anyway.

Any input is appreciated.

Have you seriously worked optimal speaker placement? makes a huge difference in SQ between done wrong and right.

I spent a week doing it (but I'm on the extreme side of the anal bell curve), from Master Set then tweaking based on my particular room, using a laser level for toe in and rake angle. Huge improvement in all areas. All it costs is time.
Tholt - the listening room was built with 2 channel audio in mind, from the acoustic ceiling paint and a few angled absorbent ports, to the no-standing-wave angles. The speakers and fat leather chair are set using the Cardas Golden Ratio or Fibonacci numbers from their excellently informative website.
The room and treatment is the single biggest improvement I feel anyone could make to any system.

Cmalak - I've toyed with the idea of Red Wine products and appreciate your pointing the articles out. I'll have to move them up in my list and make it a point to find a demo/demo location. They (Red Wine) seem very boutique-ish. One of those companies that everyone knows of, and have a friend of a friend who heard them once.... but no one ever seems to own them.
As a Squeezebox owner their forums rave about the Red Wine mods.

I think I will focus on the DAC and the Isabella may be the way to go. The amp/speaker combo has what I want. Perhaps a new streaming transport with a nice built in DAC will be a route also: Squeezebox is now owned by Logitech. While the sound is super with the DAC, I feel I should try other transports that aren't made by a mouse and webcam company.
You haven't mentioned PCs. I'd suggest trying a few. I like Kaplan Cables, and you should be able to try before you buy. The copper Kaplans will open up the soundstage.

Your ICs are ok, but you might consider trying some better ones at some point. They can have a huge impact on the soundstage.

I have a VDA*2 and it's a great DAC. It throws a very good soundstage. I didn't find it to be overly sensitive to transports. I use a Pure Note Alluvion coax for it. I don't think the DAC is the weak link.

Try the system without the power conditioner.
Thanks Mooglie. I really like the VDA2 with outboard PS. When comparing the $1600 Squeezebox Transporter to the $300 Squeezebox 3 plus VDA & PS, we found the SB3 + CI Audio setup to be an impressive pair with a much more dynamic response and more full sound stage.

I admit I haven't invested too much in power cables - I'm just skeptical. I'll look into the Kaplan's -- especially if they have a try before you buy.

As for the power conditioner, without it I go thru tubes like no ones business. I should mention that the power conditioner is actually plugged into a APC 1500VA uninterruptible power supply. The pair gives me about 30 minutes of full power run time in a blackout -- not that I'd try it. The cabin is subject to massive brown-outs.
