What integrated can replace over -bright exposure 3010?

then try a Creek

Lots of integrated now days - many are spendy - post a budget if your amp does not improve

Spendors sound great with tube gear. You should look for an integrated that uses EL34 type tubes. Years ago I used Quicksilver amps with Spendors and it was a perfect match. The Prima Luna integrated amps use EL34 tubes.

Wow I am really shocked that no one is asking what the rest of the system is comprised of?

Exposure electronics are not bright at all, they are clean, punchy with excellent prat. 

Brightness can be attributed to cables, and source components.

If you just moved into this amp is it broken in? Are you using stock power cables? 

Often when getting a new component which has higher resolution that the older component it can show you weakness that you didn't know where in the system such as incompatible cables, or an inadequate source.

Only once you know the entirely of the setup can you make commments

Thanks to all  for the suggestions. Troy:  The rest of the system is: sony 5400 CD/SACD player; gyrodec with shelter 501 cartridge; DNM cables and interconnects.
The exposure was a dealer demo and well broken in. Previously I had a Plinius 8200( warm but a bit slow) so the DNM cables which are a bit lean and clean ( like the exposure) matched very well. Perhaps its a speaker cable /amp mismatch (too much lean and clean??).I hope not since I need flat cables with a long run under the carpet and there are very few affordable options.

Your best bet upgrade interconnects and use good power cables and add a good tube  dac.  The aqua hifi stuff is amazing.
