I own a cello audio Palette on casters as Mcfarland mentions.I cannot live without it,I also have the Accuphase DG-38 in my system.The Cello is by far superior easier to use ,very user friendly and intuitive. One of the best components ever made,when one consider the price of some of the cable,the cello is a bargain.Again like Mcfarland mentions it can truly improve on poorly recorded material.Down side The audio Palette has either a single input or version IV has three I think,but not very practical if you have more than one source and if you want the equalizer to be at your listening position,that will require many long IC cables.The single input outputs use fischer connectors ,difficult to find and VERY expensive,limiting your cable options.The way I overcame these complications was by using the Cello Encore preamp which has lots of inputs to feed the equalizer.I also had my units brought up to date by Cello Germany,also adding XLR and RCA out/input to the equalizer.Another issue is service there are solutions but they are not necessarily convinient.
I am not sure this answer will be seen on forum as the audiogon monitors have blocked my last few submissions,for no obvious reason.
