Best return for the money, system upgrade suggestions please.


Hello!
I have managed to save some money that I do not intend to use to pay down student loans! I managed to save almost 2K and would like some advice as to where the money would be best spent. Here is my system below, thanks!

Amp - Integrated Krell Vanguard
Speakers - Sonus Faber Electa's
CDP - Cambridge AZURE 840C
SACD - Sony SCD C2000ES
DAC - Cambridge DacMagic Plus with BT dongle
Tuner - Luxman T117
Speaker Cable - Audioquest Type 4
IC's - Kimber Silver Streak throughout
Dedicated/Isolated 20 amp AC line with a PS Audio outlet

Hello to all,

Thank you for sharing your wisdom and suggestions.

I ended up getting lucky, I contacted Cambridge regarding my failed AZUR 840C CDP. They accepted it as a trade-in and sent me a prepaid shipping label to send it back. Then they provided me with a code to purchase a brand new AZUR 851N Streamer/DAC for half of list price. It's on it's way from CA, really looking forward to hearing it as it has received many rave reviews! Being made overseas, I hope it works out of the box. This will replace my DacMagic Plus, a weak link in my system as pointed out to me in this forum, and was purchased way below my budget, the rest goes to paying off student loans and the DacMagic Plus will be going up for sale.

I would like to add that I have read many complaints about Cambridge Audio's extremely poor customer service. In my case, I found their support to be superb. Offering me a brand new completely different unit for a Jurassic period CDP went beyond my expectations. They were extremely helpful, quick to respond, answered all of my technical questions and were very professional.

Thanks again everybody - most appreciated!

I suggest that you audition the new ADD-Powr ElectraClear or Symphony made by Coherence Systems. They are designed by the founder of Quantum Products and QRT from many years ago.
These amazing and affordable power conditioning/harmonizing devices will take your system's sound quality to new heights, I promise you. 
A second subwoofer or some kind of decorative room treatments and or bass traps.  With 2K you could do both! 
Unless your room is already done, 100% acoustic treatments! Check out GIK Acoustics stuff. No gear upgrade can match the sound per dollar spent on acoustics. Next would be speaker placement (free!)
