Hi Simon and welcome.
I made the move from an LP12 to direct drive recently, I loved the sounds that came from the old fruit box but to take it any further down the upgrade route was just too much money. I bought the Toshiba SR-370 with an SME 3009 S2 and fitted my 2m Black and I struggle to find fault with it. I would think a Techie with the Naim Aro would be pretty special but there are proper Techie experts here to advise.
I've had my Harbeth Compact 7s for about 25 years now and despite trying other speakers I go back to the Harbeths. They just give the music without adding or removing anything. I see you are in Sussex, if you get around this way you are welcome to have a listen.
