Where is the weak chain in my system?

If your preferences run to warmth and smoothness, I would second Bozo's recommendation that you try a tube preamp. That may also give you the power you seek. Start by auditioning something which is neutral tube-y like a CAT. If that doesn't pull your chain try something more 'romantic' like a Cary.
P.S.Do you have wall-to-wall carpeting with a pad? That makes a huge difference!

I would say the weakness if not bottleneck in your very nice system is the Crosslink. Beyond going up the Cardas line I do know of a good recommendation. An upgrade to thicker cable like Cross, Golden Cross or Hexlink would definately be a smooth move. Maybe some sort of power treatment would yield benefits as well. I'm just getting in to the power game, so i have no firsthand recommendations. i have heard good things about Audio Prism's quietlines, PS Audio powerplants and Monster's HTS-2000.

I think you have a fine system and might want to look into the acoustics of your room. (standing waves, 1. reflection both wall and floor etc.).
If you would like to change something you could try to go to the web site of Argento cables and take a look at their products.

They have just been tested at.

(I know, wired adress!!)
The only mistake they made, is that the price mentioned is the double of the real price, which makes it an ever better buy.
I use the VDM series myself and find that nothing comes close to it.

Ac...Ac...Ac line first ! Cardas power cords are good, but not in the game with your system, same with speaker cable, if you like Cardas;try Golden Reference.And what about your digital and inter cable? In my own system ;the digital cable is the one I switch to get the sound balance I prefer.

If I was in your position I would start with one, preferably two dedicated electrical circuits. Followed by a good quality duplex connectors. If you want to go on the cheap,Bob Crump from TG Design, recomends a particular Pass & Seymour model. You can probably find it with a search. On the more expensive, go with a Jena Labs cryogenically treated plug, list about $80.00.

On a more important line, (pun intended) I am in the process of burning in some cables in a Cable Cooker 2.0 from Audiodharma. their site is: http://www.audioexcellenceaz.com/audiodharma_cable_cooker.htm.

My initial reaction has been jaw drooping with my interconnects. I am still in the middle of trying this out with the different IC and Power Cords. If the rest of my cords benefit a tenth of what my Coincident iCs did I will be very happy.

For reference I own Rolland model 10 amp, Hovland HP100 mc preamp, Graham 2.2 mounted on an Oracle turntable. Wadia 27ix w/270, Verity Parsifal Encore. Numerous IC, and PC from JPS, XLO, Coincident, Illuminati. Don't ask me to compare them until they have gone through the cooker. This cables were "properly broken in?", not until the cooker.

You have a good system, do not change it until you work on the basics of what you have. Going on a wild goose chase can be very expensive and time consuming. I know.

Hope this helps.
