Do a 30-day home trial with your system and ears of the Benchmark LA4 preamp. Uncolored, XLR, pure silence from the tweeters, and the volume control is amazing. The volume control does click but that is a benefit for me since it has 256 steps.
Benchmark LA4 Line Amplifier - Benchmark Media Systems
The Benchmark website has had this disclaimer since 2019. They are selling a ton of them.
WE RECOMMEND PLACING AN ORDER BEFORE THESE ARE SOLD OUT. WE HAVE BEEN WORKING HARD TO INCREASE OUR PRODUCTION, BUT DEMAND HAS BEEN GROWING RAPIDLY AND ELECTRONIC COMPONENTS ARE IN SHORT SUPPLY.
I recently got a CODA #16 amp and paired with the LA4 is amazing. I just hear the beautiful sounding amp and my source.
BTW - I tried a $7.5K colored preamp with CODA, KRELL XD, Benchmark AHB2, Parasound A21+, Class D (and GAN), I always came back to the LA4. If the amp sounds good, then I want to hear that and not the preamp.
