Upgrading the "original " Rogue Sphinx integrated amp to the new version 2 (v-2)??


I have the original Rogue "Sphinx" integrated amp which was introduced approx. 4 years ago. There are upgrades now available for $400.00 plus round trip shipping. The upgrades focus on headphone output level;  increasing output level of phono stage, and general noise floor reduction,  Has any original  Rogue. Sphinx owner had these upgrades done?? and is it WORTH IT, THAT IS, demonstrates a noticeable improvement in sound quality. especially noise floor

I ask because the upgrades with  shipping will cost $600 from Rogue's factory in Pennsylvania to the West Coast ( they will not pay for return shipping).  It is a nice integrated amp, but no classic. I have considered taking that $600 and adding maybe $1100, and buying something new or used mint that is superior in sound quality for around $1800-$2000. Must have a excellent phono stage that can do both MM/MC, and be 100-150 RMS.   All suggestions and recommendation are welcomed.   Thank you

I had the original and didn’t care for the sound. Plus, it malfunctioned badly. I may have had a lemon, who knows.
If I were you, for the money you’re talking, I’d try the Job INTegrated.
It replaced $10,000 worth of stuff in my system and sounds just as good and in some ways, better.
Another thing, the Clones 25i I had smoked the sphinx in truthful tone and natural sound. I would take that over the sphinx in a heartbeat.
But that’s me. And that's half the price of the Job, and a fraction of the price of the sphinx.
To  Devilboy:  God bless, but I have never heard of either of these companies. Do you think they will still be in business in 5 years??   But, I will check them out on AG's directory.
Devilboy, Can't find a reference to the so-called Clones 25i.  Please don't pull my chain about the topic.
Sunnyjim, I've been a member for 10 years. You really think I'm "pulling your chain"?
Google 6moons review clones 25i.
And even without the 6moons search, I found clones audio easily.
Gimme a break.
