HELP Monitor speakers for vintage components????

TOTEM DREAMCATCERS !!!
Check the Stereophile Review, if anything the reviewer is understating how good they are.

JBL 4312 in mint condition can be found for half your budget. They're outstanding.

If you liked the SPENDORs with their particular signature sound, hifishark.com has a bunch of used ones listed for approx. 400 + Euros used + shipping.
You can also get USA new/demos for $US1200 ($1800 new)

I've had both the TOTEM ARROS and FORESTS in prior systems (both now long gone) and IMO and experiences --- for sure --- any TOTEM product will be much more fussy about accompanying equipment and also result in a radically different signature sound that that "classic British" SPENDOR sound you like ..... Not even close .....

Your takeaway: if you liked the SPENDORs, either go get 'em again or substitute with a close relative British speaker manufacturer. e.g.: Tannoy, KEF, ATC, REGA, just to name a few in a crowded arena of competing products.

Of course, you already know that (1) system synergy matters big-time, and; (2) you cannot escape the basic tenet in this hobby: you get what you pay for.

I have owned the Spendors and I thought they were a great little speaker. You should be able to get a used pair for under $700. Just be patient and a pair will come up!

Be patient and snatch a used pair of Totem Acoustic Model 1.
