Well, they are wrong, such is the problem with forums these days !
Personally I don't think the PCB damage is anything to worry about. However if you mount the resistors (even the very same ones) an inch or so off the PCB, the heat generated will dissipate and not be so intense right next to the PCB.
That's the thing Dave, they are already mounted a good three quarters of an inch off the board. Ah well, they've worked okay up until now so I guess I'm worrying about nothing when push comes to shove...
Okay guys I replaced the blown Coles in my DM2's this afternoon and frankly I found the job very stressful. It works but the damn things are so very delicate that for a while there I somehow managed to convince myself I'd fooked yet another one up so as a result I've come to a rather drastic decision. Due to my innate clumsiness I have decided to sell both the DM2's and the Skibo's, which should allow me to source a pair of speakers with Dave proof tweeters. I will be very sorry to see the DM2's walk out the door as they are quite the nicest sounding speakers I've ever owned, however I need to be both practical and honest with myself: It is only a matter of time before I do something stupid and blow yet another pair of supertweeters. Honestly, I can't keep shelling out nearly 100 notes for these things whenever my common-sense is out to lunch
I am really enjoying the Mission 760i's in my near-field system just now, the only area where they lack in comparison with the DM2's is in extreme bass extension, in all other aspects they equal the DM2's. The Missions are quite unforgiving of poor quality recordings unlike the DM2's but I can live with that for now. I own a pair of Atacama SL400 stands which supported the DM2's so to save on spending extra cash their replacements will need to be able to sit comfortably on these stands. Rear ported speakers are a definite no-go in this room so whatever the replacements are they must either be front ported or inifinite baffle designs, any suggestions? The budget will be around the 400 to 500 quid mark (once the Skibo's and DM2's have sold) so that should give me a fairly decent choice on the used market.
Not off the top of my head Chris but if I can get close to what the 760i's are giving me but with a more extended bass I'd be over the moon. There are a very nice pair of 770 freedoms on ebay just now for a BIN of £195. They are in lovely condition and although it has been a very long time since I heard a pair I remember being impressed by them, memory is a fickle thing though. 400 to 500 quid could get me something really special I think. Whatever I get must sound good at low levels, something which the DM2's excel at.
Good luck with them Dave. I've never heard those Tannoys, but I'd be surprised if you will get the quality of bass from them that the 3a will give you. That's the beauty of those old ARs - they have a 'snap' to the bass that is rarely equalled in a speaker of that size. Anyway, maybe you're not looking for those sorts of qualities.
