I have used dbls for last 6 years with cheap (ish) gear . Bought used but with new bass drivers /passive xover . Guy I bought them from agreed to set them up but unfortunately when dosh (asking price ) went into his bank he refused ! Ok he did back track big time afterwards 'really want to help' etc but by then I had 'set them up' as best I could and opted to have nothing else to do with him as trust blown.
They are on castors , in a smallish room with high ceilings , driven by ancient (1979) exposure iv amp single transformer , other gear helius viridian/rega/AT anniversary /4 box trichord phonostage / audio synthesis passive on unconventional supports (maf stands on brick/concrete/towshend stuff etc). I liked the sound from the word from word 'go', easy , clean , communicative with an odd ability to convey the energy of 'live music' to my ears . Compared to how they sound now they did sound 'undynamic' , now very dynamic since using nos nac 5 and naim speaker plugs so I would cite 'breaking in' as relevant. They really do it for me with classical symphonic music mainly due to the scale/dynamics/clarity. Detail retrieval best I have heard on my records, not forward or harsh etc . Quite good depth . Foam covers now shit but tweeters sound nasty without some sort of covering. May sound odd but they do remind me of quad 63s but with scale/dynamics etc. I did try to sell them once as a stunning looking pair of lowther auditoriums came up but were quickly sold . Active ? Maybe when things settle down (if ever !), previous owner did have a bass driver blow on His active set up (500s) and apparently naim could not explain it so not that keen . Also have used the headphone jack of a roberts radio to play classical stuff through them with acceptable results .
My intention was always to 'upgrade' the amplifiers but there always seem to be financial constraints so am happy with what they are .
