Amp/ receiver advice for Spendor SP2/3's

I have used Spendor's since the 70s and would second the "No Receiver" resolution. The British Fidelity amps were very good with Spendors , I use to sell both. British Fidelity was a name used in the US by Musical Fidelity during a period in which that name was trademarked in the US by another company. Their products are , of course , still on the market and are excellent but they have gone up market. Since I do not know your budget I cannot comment but would suggest that a good used tran. amp would probably be better for your current needs than a tube unit.

I recently picked up a pair of Spendor SP2/3 on the advice of a friend.  I have not had any real stereo equipment for a while and, on a budget, I went out and purchased an NAD D3020.  Its a nice little class D amp and the speakers sound pretty darn good but I want more depth and scale in soundstage.  I am toying with buying a Peachtree Grand X1 but not sure if it is overkill.  In theory, would these speakers be a good match for an amp like the Peachtree X1?  The "rated power handling" on the SP2/3s is 100watts and the X1 puts out an awful lot more than 100watts.  Would it be overkill?

These deserve high quality amps and source as other have said.
I run a pair of SP2/2 with vintage 35watt tube monos and they sound great. I have also used a brutish 70watt KT88 tube amp and found they responded well to more power. 
@gjuliani as long as you don't overdrive them, the X1 will be fine.
