Best bang for buck integrated amp for $500

I’d say first off - you’ll have to let the IO run in for at least a week. Let those transistors settle down after shipping and everything burn in. Listen to it for a week or 2 and then switch back and see what you think. I’d expect the bass to open up for you as well. Especially since you like the tone and clarity. 

Okay I'll try that but I'm not a big believer in burning on amplifiers speakers yeah because there's moving parts but transistors heating up and cooling down I'll give it a try but I'm not a big believer in it.

I do like the sound of the io it's just lacking base I really wasn't planning on having to add a sub but we'll see I'll give it a little more time.

audiomike,

Please let us know how you get on with the IO.
Curious if the sound improves after  break-in.

I'll let you know if the sound changes but I won't hold my breath because I highly doubt it's going to change it is what it is.

Been running my Rega IO for hours and hours and it had 15 hours on it when i bought it.  I think the sound is what it is now it aint changing.

I like it for the most part, is it perfect no, but no amp is.  It has little things that could use improving as far as function goes.

The sound is good, do i think it could be better yes, am i going to say this is a fantastic amp, no im not.  Im going to say its very good, but not great.  Like i said before it lacks bottom end  to me, thats my opinion on it, your view may vary.  There is bass of course and what bass it does produce is good and tight and works, theres just not enough of it.

Im searching for a sub to add, and no its not my Triangle speakers cause with other amps my Triangles have very very good bass, its the Rega.  I dont want to sell the Rega and lose money and keep playing the search for amp game.  I think adding a sub will address my issues, cause the mid range and treble are very good.

I will live with the small issues i have with function, like cant read the numbers hardly to tell what setting your on, dont like the on/off button, the volume dial very hard to turn.  I can overcome those things, the amp is a little blah looking, i can deal with it. Love it fits on my desk and its small footprint, it has good very shocked power for only 35 watts.  I am yet to try out the headphone jack, i have heard its good, i sure hope so.

I just realize trying different amps how much they vary between differant brands, i will say in my getting the Triangles Bro 2s speakers the best amp pairing so far is the Emotiva Basx A100.  I sold it cause the headphone output sucked and i thought i could improve on it as far as sound, and now going down the audiophile rabbit hole.  Im done sending amps back and losing money on return shipping chasing a perfect sound, im over it, i will keep the Rega IO.  Is there a better amp out there that could fit on my desk or small footprint and out perform the Rega, im sure there is.  Its time to content with what i have and enjoy it, im adding a sub and im done.

I thank all of you for your suggestions and input and helping me decide.
