The Harbeth's you have are the ones to keep unless listening room changes require more scale, or you just like spending money because you have enough of it that your kids and spouse won't suffer any needs denial because of it. As our friends in the UK usually pay more for North American manufactured audio components, so we pay more for their audio gear. I have two acquaintances in London area who own Harbeth's and we've had a good laugh at what I paid for my Harbeth's vs what they paid for theirs. I laughed at what one of them paid for a Pass Integrated. I have saved letters off internet forums from Harbeth/LFD retailer raving how fantastic C7's were, how fantastic LFD Mk III was, and lo and behold when newer NCSE and 30.1 appeared on market now the C7's and LFD Mk III are "fuzzy sounding" and/or "broken sounding" compared to the "much better" 30.1 and NCSE. My takeaway is keep your discretionary funds in your pocket and not in the pocket(s) of those paying for their spouses Botox treatments, kids college funds, restaurant dining, or whatever else it is that motivates audio sellers to make dubious claims. Like car dealerships, audio sales people are always ready to upgrade you to the new model.
