Purchased from Audio Venue (it was their ex-dem model) - the amp is in 10/10 condition and is around 1 year old. Comes with around 18 months warranty and happy to support new owner in any way. Selling as I'd like to try and find a lightweight alternative - I'm too old to be dealing with 20 Kgs amp these days. Not desperate to sell but if there's interest, great. Would be interested in a trade (+ cash) for something like a Devialet 220 Expert Pro CI. Amp can be collected from Whitstable, Kent or happy to meet at a mutually acceptable location around M25. Fully insured shipping is possible - will be around £80. price is £4500 ovno.
