Best amp/ IC's to go with my Thiel 2.4SB's


Hello All,
It has been many years since I have joined in on the forums, sadly it was because I sold off all of my Ayre components, but fortunately I kept my Thiel speakers. 
As for the amp question I pretty much know the answer before asking, the Ayre V-5Xe. That is the amp I previously owned. But just like before I am at the crossroads of do I go with an Integrated or a stand-alone two-channel. Before I started with the BAT VK-300x SE, Ayre A7-Xe, and finally the Krell KAV-400xi. The Krell out of the three Integrated s performed the best as I was completely surprised at it's power output and ability to drive the Thiels. Then when finances allowed I purchased the V-5xe and the Ayre K-5Xe pre-amp. I have a shot at another V-5Xe, except this one is Black (originally a $250 up-charge) for $2,750 from the original owner.
My second question is at the time I went with AudioQuest Cheetah XLR IC's they were second from the top at the time. I always like the neutrality of AQ's when it came to their sonic footprint. But after working for 5 years for a local company, which will remain unnamed. I found out what many people don't know and that is that all of AQ's cables are marked-up aprrox. 300% from what an employee would pay. Now to me I just won't pay that kind of money I would rather buy something used at half the price. With that being said since I was last in this game I see the Siltech cables which from what I read are high quality and very neutral. Can anyone give me a fair comparison between AQ and Siltech .
Finally, I am trying to decide if I should go with an Integrated first. The only reason I am even considering this is because I have found a very clean Ayre K-5e pre-amp but to be up to date it would be $1,200 to send it back to Ayre to have it brought up to the present K-5 xeMP pre-amp that sells new for $5k. I am looking a a 5 month old Music Fidelity M5si, they are asking $1,500 but is accepting offers, I figure $1,250. It being rated at 150 W @ 8 Ohms and only puts out 265 W per channel @ 4 Ohms.
Sorry for the long thread but I greatly appreciate your input.
Thanks,
David

Buy the Ayre V-5Xe and K-5e. This is what you have tried and are familiar with your Thiel's! Excellent amplification! Keep the K-5e stock (it is already a superb preamp!). Regarding IC's: contact HCM and see if they have any left of the AQ Silver Extremes (list $400). I paid $100 new for mine (5 pairs - $500!). A superb IC!
AQ might be marking up 300%, but do you think any other manufacturer is going to be selling their  product at a lower markup?-esp. if it is highly regarded.
Business is business, and making money is the name of the game.

Why not just buy used and save on the depreciation?
I agree with roberjerman, get the Ayre-you can always upgrade later.

The only question I would offer an option to is the interconnect question.
Although you will receive many different answers, IMO I would go with the Cerious Technologies Graphene interconnects or their newly released Matrix interconnects depending upon how much you want to spend.
Yes, the Matrix is more expensive but extremely good compared to the Graphene interconnects which are good, and for the price a killer interconnect.
For interconnects I would try these they are very good irrespective of price. No affiliation just a satisfied costumer.

As for an integrated I would go with Pass but they are fairly pricey. The Thiels like a lot of current to sound their best and the Pass can provide that.
