Narrowed it down to two Monitors, Dyn Heritage Special, or Wilson Tune Tot

@erik_squires is correct. Over time both the Tunetots and the Heritage Specials will almost certainly depreciate in an amount very close to the total cost of a pair Fritz speakers. If your decision is being driven by trying to balance cost/benefit then by all means, there will be alot of choices out there that will make better sense if comparing retail-retail. Then you have the value that buying preowned can bring to the table. Then you have the value that buying a kit and assembling something yourself....there will always be a better financial choice, depending on how hard you are willing to work at it.

@erik_squires prefers Fritz given his cost/benefit evaluation, I prefer the Tunetots and most likely the Heritage Specials over the Fritz or other similar footprint/purpose speakers. Yes, I have heard Fritz although its been a number of years so no direct comparisons although when you can buy whatever you want within reason (which most Audiogon members can and do) then we do.

When I started to put my system together a few years ago I ended up with the Tune Tots because I felt that their highs were better than the other bookshelf speakers that I was able to audition. The others that I listened to, were B & W 805D,  Vandersteen 2ce sig, Focal and Spendor. I no longer remember the models of the last two. Mine are paired with a sub system. They do cycle quite low for their size but IMO the 5.5" woofer is too small to cycle that low with any real authority so I have mine crossed over well above 80Hz to prevent any woofer damage during louder listening sessions.

I have not heard the Heritage so I cannot compare them.

I own the Dyn HS - great speakers.  The 7" woofer goes reasonably low and I don't see any issues with resolution.  In my small room, they go down low enough to not need a sub.

@erik_squires I agree on the TT resale, not the Dyns, they tend to hold better, especially those models in short supply like the HS. Resale isnt driving my decision, it's truly the sound, but some of the lesser known names drop in value and are hard to move it you wanted to. I get your point on spending less though. Appreciate the advice for sure. 

@ghasley thank you so much for your input , super helpful! I have the Heritage Special, I actually went ahead and bought them today so they're mine now. I coordinating bringing in a traveling set of TTs from Wilson so I can have a listen. If I like them I get full trade up value to the TTs so I am not worried either way. You are going to like the HS, they really are quite nice, and obviously I can't compare the two and have zero audible memory of Wilsons sound but I will be interested to hear your impressions of them. Like really interested! 

The Fritz Carrera B's would go splendidly with your Sugden.  I heard them driven by a Modwright 300B headphone amp, so they would respond admirably to SS Class A.
