Chazro. I owned the SP100's for several years and only sold them when I moved the system to a room that couldn't handle their size. I've also auditioned the VR4JR's extensively. I'm always cautious with these types of things because so much is system dependent and much relies on personal preference. For me, it isn't even close. The Spendors were the best speaker I've owned (and I've had quite a few). The VR4JR's strike me as more of an audiophile speaker (i.e. one that images well, does all the hifi theatrics and checks all the boxes but simply does not make music like the Spendor. There's a reason why you've kept them all these years--they are that good. Having said that they are probably showing their age after 15yrs. Depending on room size you could replace with a pair of Harbeth Monitor 40's which are identical size but will sound even better or go with the slightly smaller Harbeth HL5 Super's which will sound better than your Spendors except for the deepest bass. If you like the Spendor sound I do not think the Von Schweikerts will be your cup of tea. They certainly weren't for me.
Spendor vs. Von Schweikert?
I'm the very happy owner of a pair of Spendor S100's. I bought them new 15 yrs ago. My system's evolved over the yrs from transistor to all-tube and thru it all the Spendor's always sounded rich and musical, very satisfying to my ears. I think that the tweeters may be showing their age (or maybe it's my ears!;) but I've been contemplating a change. I've read so much about the VR4Jr's, I need to audition them somehow, but thought I'd throw the question out there. Anybody familiar with the sound of both these lines? How do they compare?
