Anyone ever upgraded from a Konnekt48?

I know a few here have used the TC Konnekt48 in the past.  I still use and like mine but as it's getting a little long in the tooth I can't help but wonder if it's time to consider upgrading.  I always kinda keep my eye open to what's out there and what I see are things like the Saffire Pro40, 56, etc., but they actually use some TC technology (jitter, I believe) so I'm not sure it's a step up. Plus the Konnekt for it's price point has an unbelievable amount of i/o as well as the remote.  Dynamic range is 100db which was probably great when it was new but lags behind even budget interfaces now, if that even means much.  I understand quality of conversion and the circuits around it are as, if not more, important than just the spec itself.  So I was wondering if anyone has upgraded from this specific interface?  The zoom uac-8 looks interesting at a comparable price point.  I'm not opposed to staying with firewire as I have a card in my PC already.  I also have USB 2 and 3.0 so can go any way.  I'd like to keep the same style of interface as well, 1ru, similar ins/outs, etc.  Not really interested in modular units like the Audient stuff or uac-2 or tac-2.  It seems to keep a comparable format and i/o I'd need to look at something like the RME UFX or Apollo 16.  Anyways, just thought I'd ask. My Konnekt is still chugging along but since it's discontinued and quite old, I think I need to start thinking about another one...
Thanks.

Agreed.  I had a Konnekt 24D (little brother to the 48) that sits in my closet as a backup interface, and still use two Konnekt 6's for various audio-listening tasks. Those TC Electronic units are something special (features and high-end specs), but because of long-standing driver issues, a lot of users got tired of waiting and dumped them on Ebay.
 
They finally did iron out those drivers, but yeah, too little, too late for many.  I ended up going to Steinberg interfaces, which was about a lateral move specs-wise.  But my next interface will be an RME.

Lol, ya, if I had the money. It'll likely be rme for me as well but even used, the UFX is still about 2X what I paid for the Konnekt48 new. And that's without the rme remote unit. And forget about the new UFX+, I'd love that but $$$ (and even then, the Konnekt48 has more physical analog I/o on the unit).

I guess a ucx could sit on the desk while adat ins could be in the rack. If I went used I'd probably try and sniff out a ufx or apollo maybe.
Edit: Just looked at a Lynx Aurora 16, impressive but again, would need to find one used...

Yeah 2nd hand Konnekt48s run about $600-700cdn. Lynx units are still $1500-2000cdn from what I've found. So are the RMEs and Apollos. I wonder how much of a "night-and-day" difference there would be (if any) between the units...

I don't know why it posted 2 replies...

I hear you. I have Seventh Circle pres here, plus a Soundcraft M4 AND the Konnekt's pres so pretty happy with that setup. I'd even put the M4's pres ahead of the Konnekt's. I'm sure there's a sonic improvement in the pres of a higher end unit. For that matter, the D-pres on the Yamaha mixers and Steinberg interfaces are better, at least to my ears. Not that the Konnekt's are bad at all. They're quite good. I know at some point everything's going to be obsolete, just feel like I'm nearing it for the Konnekt. Who knows, maybe Behringer will resurrect it as a cheaper Euphoria48!
