I owned a pair of rtl 2s ages ago. I was bitten by tue upgrade bug and sold them to buy the latest what hifi award winners of a similar price. Big mistake. Not only was it a mistake to try and replace them with speakers of the same price but also speakers over £1000. I now own a naim based system and ive spent years trying to find speakers that sound like the basic (un modified) tdl2. I now own linn keilidh speakers with the upgraded tweeters endorsed by linn (from £6000 linn keltiks) and they still dont have the mid range capabilities of the rtl2s. Am seriously considering buying another pair but the voice coils would fry.
