@smodtactical If I too may offer a supportive angle about value and quality of sound some of the smaller lower-volume production builders offer. When we lock into a special preamp or special amplifiers, immediate resale value becomes less relevant because we choose to keep these units and listen them over decades vs. years.
Looking at photos inside of Aric Audio amps and preamps some can see what’s going on there and what makes it extra nice in terms of parts, hand-made layout, construction. Something most of the mainstream manufacturers won’t offer due to higher labor costs. Lifting the hood and looking underneath, comparing, comes next once you learn more.
Even the lower priced (Aric Audio 6SN7 Linestage) is nice, can use different tubes for different sound and presentation, another option if you don’t like tube swaps in your current ARC ref5se. And, we’ve got the designer/builder right here on this forum. This is value-add $ for those of us who seek out the better boutique builders. I’ll go out on a limb to say its likely Aric can get you closer to the sound you seek. Another reasonably affordable option if the your existing preamp does not work out for you.
