Integrated Amp Recommendation

I'd get a 2nd opinion on the repairs first, especially if you like that unit. 

I have owned a couple of Peachtree's integrateds (the Grand X1 and Nova 300).  If you need a lot of power and a lot of bells and whistles (DAC, headphone amp, HTPB, phono) the Nova 300 is really nice and you can find them close to your budget.  They're both great sounding units and very neutral. 

Ultimately, I replaced both, "downsizing" to something more simple.  I replaced the Grand X1 with a used Audio Research VSI55 (love the tubes!) and replaced the Nova with a Heed Elixir ($1200) which I think sounds better than the Peachtrees.

Thanks for all the great feedback!  My 804's are 15 years old, made before the diamond series was introduced.  I open up my Musical Fidelity integrated and sprayed contact cleaner on the volume control, but that didn't solve the problem.  The Musical Fidelity distributor informed me that it's normal that the capacitors will dry up after 15 years or so, and was not surprised that they need to be replaced.  I trust the tech service who gave me the estimate, although apparently they have a reputation for being very expensive.  But then there seems to be no one in New York City who can do it for less.  

Does anyone have an opinion on whether the new Musical Fidelity integrateds are as good as the old ones like I have?  The tech guy, who seems honest and very knowledge -- and a real purist -- feels the old ones are better, with a warmer sound...

No decent quality cap should "dry up" within 15 years. I'm not sure about their older integrateds but their newer models use cheap, Taiwan-sourced caps. 

It appears as though the volume pot in your amp is located toward the middle of the chassis. It has a tube that transfers the torque from the knob. Did you removed the cover and spray into the actual pot?

Get rid of this amp. Yes, after 15 years quality capacitors should be alright. I have 20 years old Audiolab integrated and 18 years old Australian Redgum integrated. Both work as they did years ago. 
Analogique in New York City ?
