ARC 100.2 Enough power for Proac 3.8


I am looking for a power amp with plenty of grunt to drive a pair of Proac 3.8's.
Currently they are being driven with an Ayre V-5x which has been kindly lent to me by a friend. It sounds gorgeous by the way, but could use a bit more "slam" in the bottom end. It's damn close to perfect though.
The catch is that I can't afford one of those beasts and have read good things about the 100.2 from ARC. Could this be the beast I am looking for or do I need more power. The Ayre is 150watts and the ARC is 100watts but apparently belies it's output rating. A VT100mkII is also tempting but I'm not so sure about the tube approach.
Any other suggestions would be appreciated.

I ran a pair of ProAc 3.8s with the VT-100 MKII for 5 years. A great combination which makes wonderful sound. More than enough power too. At one time I did try a 100.2 but found it very uninvolving and sterile compared to the VT-100 with the 3.8. I would go with an ARC tubed amp like the VT100 with the ProAc.
I'm running a pair of ProAc RS2s with a pair of ARC D250 Mk IIs (each bridged to mono) in my study and a pair of 3.8s off a pair of horizontally bi-amped ARC VT 100 Mk IIIs in my main rig. I was also using an ARC D400 Mk II with the 2s downstairs for a while, but the 400 went upstairs to the pool room to power another system. While I prefer the 400 over the 2x240s, I'm just not gonna carry that gazillion pound monster back down four flights of stairs.

Oh, I would def. recommend the tubes for your 3.8s. I've tried the 3.8s with both ARC solid state set ups and the VT 100s and the VT100s are the hands down winners... Much more musical.
Edesilva, looks like you have lots of ARC/Proac experience :-), and you have touched upon a subject that has interested me. You mention that you also use the D250MKII amps. I know of a local friend with one for sale and a monster it is. I am a little leary of having to retube this creature (16 tubes!!!!) I didn't know they could be mono blocked yowza!!! Do you prefer these amps to the VT100's? It would cost me around the same amount for the D250MKII or the VT100MKII, is there something special to note about either? As I am still into solid state and the D400mkII is still of interest, can it be mono blocked as well?
Thank you all for your replies as it is a great help in designing a top notch system in my budget range.
If you already have great synergy with the Ayre you may consider getting a PAIR of quality subs and "dialing in" the low end according to your preference.
I have stereo DIY subs using Adire Tumult drivers which gave me the bottom I was after.
Kevin Haskins of www.diycable.com is offering Tumult subs in a VERY small volume sealed cabinet (higher Q, but not the monsters I have). The drivers are pricey at about $450 each, but are incredibly powerful and accurate.

I have no connection whatsoever with Adire or DIY cable. I'd just hate to see you break up a nice marriage of amp and speakers, such a crucial element in good sound.
