The good news, is that you have a wonderful pair of speakers. The difficulty you have is how to fulfil their potential. FWIW. Here is my advice:
- Ultimately, you are looking at Amps in the £2500 - £4000 (New)
- You also looking at a Source in the £1000 - £2000+ (New)
- Take your time and investigate the brands of Amp which you like driving the SFs
- When you have come up with your ideal system, then come with a plot as to how to achieve it. Don't waste money on a halfway house, box shifting route. Buy once; buy right.
- Like you did with the SFs, look out for ex-dem/open box/ used, from a dealer...like I said, there is no rush.
On the Source front, I would recommend the Linn Sneaky/Majik DS....but other options are available.
Amp brands you might consider would be Arcam, Pathos, Electrocompaniet, Ayre, Sugden, Musical Fidelity, Luxman, Accuphase.
So what I'm saying, is stick with what you've got until you can do justice to the speakers....starting with a decent amp....all the while, do a lot of listening
