ARC 100.2 Enough power for Proac 3.8

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.

carver lighstar 2.0 very easily thanks

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.

Jb0194, It's not that the 3.8's don't have bass, they actually have a beautifull bottom end in my room. I like the Ayre a lot and if I could afford a pair of them it would probably be a no brainer. The fact is the Ayre is a loner from a pal until he gets room for it in his place (renovations) I could never afford one of these bad boys!!! I have heard a LOT of amps in my days (just not the ARC's) including huge Krells and Classe's but the Ayre just makes good music. Until the day I can afford one I have to look eleswhere. I am hoping that tonight my buddy will lend me the ARC D250MKII tube jobby to drive the speakers. I have to admit though that I'm leaning towards the ss D400MKII just for ease of use.
By the way Adire does have some really nice looking stuff and the DIY thing has always been of interest. I used to build my own loudspeakers but find time a little tight these days. If I was to do it again I'd be looking at those GR Research Line kits or the Linkwitz dipole. I'm certain they offer excellent value.
Again thanks for the replies
