I have a very nice Audio Research LS-1 line stage for sale in 8/10 condition. Looks great, functions perfectly, sounds fantastic, no issues whatsoever. If you are looking for a ARC line stage this may be the best choice for the $$. Included is a very good sounding Amperex orange globe 6dj8 with a-frame getter. Ask about other high quality vintage Mullard and Amperex 6dj8 I have for use in this unit. Not much on the web about the LS-1, but some say it was one of the best ARC line stages and not the lower end of the product line as the 1 may suggest. Check out the ARCDB for specs, etc. Original packing box and packing materials included. Double boxed for safe shipment thru UPS or your preferred shipping method. Payment thru paypal is preferred, money order ok too.
