Tube amp on the IRS Beta

Hi there,

I want to buy a pair of ARC VT150se and I want to let them run with the IRS Beta''s on the high/mid's (tubes is what Arnie Nudell advices, are these the right one's ?)

now the Beta's high/mid's pannels go down to a 2.5 ohm sometimes, can the ARC VT150se handel that?? without any problem???? Yes! oke than... NO ?!? witch tube amp can??

Any feedback please....

THX very much
