Ascend Sierra 1s to Harbeth 7ES-3s?

Don’t get me wrong, the Sierra’s are nothing short than a great speaker – especially at the price point of under 1K. The lower end is fantastic, dynamics are impressive, and the top end is smooth with no etching. With this being said, I’ve always been moved by a lush and romantic midrange, which has continually encouraged me to google: "Harbeth 7ES-3s."

Here’s the current setup that’s currently in flux:

Conrad-Johnson 2300
Parasound P3 (looking to upgrade to a CJ PFR)
Music Hall Maverick
