What integrated can replace over -bright exposure 3010?

First - put a good power cord on it, I mean good not $100 something.
If it is new, the cord, give it at least 300 hours of burn-in time.
Second, or at the same time - put good interconnects on it, the same company as the power cord, the higher in line the better, 200 hours burn-in time.
This amp should not sound bright.
I would probably try Audio Art Classic interconnects, $100, and power cord, $150- $350. The Classic is a very good cable, I just tried it. Don’t expect too much from it though, but it is quite clear and balanced.

I began having this issue with my Spendors, I actually think it's due to recent changes in my ears, but regardless, switching to a Yamaha integrated amp was the fix.

Highly recommend the JOB INTegrated, built in Switzerland at the Goldmund factory. And yes it is spelled that way.

I am a distributor for audio but we do not bring in this product because it is a direct sale. The built in dac is also very good.

Cheers,

I assume you did, but still have to ask - did you give a good 24 hr. warm up before critical assessment? My old reliable stand-by ADCOM GFA 5500 sounds a bit bright and forward until fully warmed for about 24 hr. and then settles in to sounding quite nice. The amp (integrated amp) I settled on - after many hours of home listening - to pair with my Maggie 1.7s, is the Rouge Cronus Mag ll. With the KT 120 tubes, is very dynamic, open and detailed with just the right amount of smooth and very musical. I know allot of tubers love the EL 34s but, in my system, just a bit to milky for me. If you can't get your Exposure dialed in - the Cronus Mag. ll might be an option. Like your Spendors, the Maggie 1.7s are very quick and detailed and the Cronus does a very nice job with them.

update:
Since others think this amp is not bright I thought: what else  do I have that they don't?
Answer : a different power cord. So I swopped out my after-market Pangea cord and repaced it with the generic-looking cord that came with the amp.
Result: brightness/glare  toned down a bit, at the cost of a little bit of impact/prescence.
Why?? I have no idea!
I knew power cords could affect the bass response but never thought it would affect the treble.....
