You can bi-wire any amp and the following are two methods:
1: Use 2 banana plugs per amplifier output socket with one banana plugged into the back of another. You need banana plugs suitable for this and extra space behind your amp.
2: Use 2 spade connectors per output socket. This usually requires soldering first and check if your amp accepts spade connectors. Any amp I ever owned had provision for both the methods above.
I am also a new owner of the Denton 80th editions and they are so much deeper and richer in the bass department than my previous Monitor Audio BX2 bronze. Overall these speakers jump up a league from the BX2's. They are built like a tank and simply beautiful. They would help the sale of your house!
The 80th's simply cry out for powerful and quality amplification. I am currently driving them with an Arcam A18 although I think an additional Arcam power amp with the 80th's would be a serious improvement again. The A18 is rather good but a little laid back and I like my music to hit me in the solar plexus. I'm not sure whether to add a 2nd hand Arcam P85 power amp or change her out for a Rega Brio.
My motivation for buying the 80th's were as following: £250 new or around $375-400 US new just because the Wharfedale decals were slightly sloping. The other is because I have Tinnitus and the metal drivers of the Monitor Audios were hurting my ears. This isn't as bad with the 80th's.
I could also do with a DAC as I am using a good 20 year old Cambridge Audio CD4 CD player which was designed by Pink Triangle although it is a budget unit and doesn't match my turntable: Customised Thorens TD160 with Rega RB300 tonearm with Goldring 1022GX cartridge. I demoed the Rega DAC and it was good, much better than the Arcam rDAC and only slightly inferior to a Linn streamer costing around £2000 GBP.
Bad points about the 80th's: These will urge you to upgrade partnering equipment, especially in the amp department. I'd love to plug a pair of Krell mono-blocks into them with a valve preamp
