Crossover resistors redux

From time to time there are threads here concerning xover resistors. In several of them, I have recommended Caddock MP930 thick film resistors with a heatsink, and the reaction was mixed. Some inmates found them suitable, others not.

A few months ago, I rebuilt my passive xovers and used Caddocks exclusively at every position, four in all. There is only one in series with the tweeter, the Scanspeak (formerly Peerless) Discovery HDS. I was impressed with the amount of high frequency detail, but there was always a bit of shrillness to high strings and sibilance on vocals. Cymbals sounded excessively hissy without much ring or depth to them. During extended sessions, I found myself somewhat irritated by the highs.

Just last night, I replaced the Caddock in one channel with Mundorf MOX, which I have also used in the past. After playing music for only a few minutes, I noted a much more relaxed and musical presentation. Vocals became richer, cymbals had a spacious ting upon being struck and rang smoothly. Strings also became sweeter and better defined with greater depth. There was a very slight loss of overall detail (or perhaps a reduction of excessive detail), but dang if this doesn't sound a lot more like music instead of some electronic reproduction.

So I'm retracting my previous endorsement of Caddock and now going with the Mundorf MOX. They're cheap (which is not critically important to me but still a factor) and readily available in lots of values, and I do believe they're more musical than Caddock, more accurate than Mills, and superior even to Duelund, which I found a bit dull and washed out. The only "major" boutique type I have not tried is Mundorf M-Resist.

Peace,
