Parasound HINT vs. Bryston 135-3 or Simaudio 340i D3PX


I have a Parasound HINT integrated amp and am considering replacing it with Bryston 135-3 or Simaudio 340i D3PX. Both options are available used at about half of new retail price. I am aware that the Parsound is considered good value, and I appreciate what it does, including the useful options for managing subwoofers in both HT and two-channel applications.
For those here who are familiar with the Parsound amp and either or both of the Bryston and Simaudio integrateds, will you please tell me what I would gain with an upgrade?My listening space is a basement room, approximately 20' x 20'. I have Harbeth Compact 7es3 speakers for left and right channels, along with two Rythmik F8 subwoofers. My primary source is an Oppo UDP-205. Cables are Audience, with Furutech power distribution.
If I would do better with a speaker upgrade than a more expensive amplifier, please just say so. Thanks for your input.

Thanks to those who have responded already with different opinions to consider. 
As for desired changes or improvements, I am hoping for improved soundstage depth at least. I recently added one Furutech NCF Clear Line unit to my system, and that has improved the apparent separation of instruments and voices in the soundstage. 
I have been fortunate to acquire much of my system at reduced prices, and I have tried to prioritize value, which is a reason that I chose the Parasound HINT amp. If improving on its performance will cost far more than its price, I would rather save for a more costly upgrade than to spend money on incremental changes. 
For a speaker upgrade, I have looked at Spendor 7.2 but read that its midrange is not on par with more traditional Spendor designs. I really like the Harbeth Compact 7’s but realize that I could buy better speakers. I would rather not buy speakers that have a significantly larger footprint. I listen to jazz and rock for the most part, and I am not a basshead.
