Bought a new McIntosh amp


Hello folks !
I just bought a new MC152 and now having doubts about my decision. I currently have Rotel RB-1552 mkII / RC1572 setup driving a pair of Paradigm 800f. I have not opened the sealed box yet because I’m thinking of returning the amp to be exchanged for new speakers (Klipsch) and an Rotel RB-1582 amp (more power 200w p/c).
While at Audio Advice store, I went in another demo room and listened to a Heresy IV driven by a different McIntosh setup ( MC462) and I was impressed but the mind was still on the path of getting the mc152 instead of replacing speakers.
Is it safe bet to just keep the mc152 and get a feel of speaker change later ?
I’d like to hear opinions good or bad about the MC152. Thanks !

If you want to try a McIntosh in a budget, take a look at the MC7104 I have for sale.  Four by 100watts  at 4 amps and 2x200 at 8 amps when mono bridged.  Plenty of power and a real deal because it uses lights on the front face instead of the needles.  Listed at $1400.  Maintained and recently cleaned and tested to spec.

And I have Heresy IV speakers.  You will never get to midnight on the volume and there will be tonnes if headroom.  
Thanks for the offer, claudiowalker77.

I don't buy used power amp but will do on pre-amp. The heat gets on the electronics more whereas pre-amp stays cool with SS and even tube pre amp doesn't get hot but only warm.

Also, the tube amp that beat the 240 was equipped with Sansui output transformer and that what gave it the edge against the mc240. We were hand winding our transformer before we found the Sansui made transformers.
All had 6L6GC tubes including the mc240.

Hi Switchman! 
I read your post. It makes no sense to own a McIntosh amplifier if you have Paradigm speakers. The Rotel amps are exceptional for the money. Especially the new Rotel amps with decent DAC's, and balanced connectors.

 If I were you, I would return the McIntosh amplifier. There are so many speakers to choose from. Going for a pair of B & W, Totem, or PS Audio speakers would be a much better audio investment compared to the new McIntosh amplifier at this point. Put your money Into speakers first. For most of us, we have to budget our audio purchases one at a time. That’s the way see it. 
You have purchase a very significant and important piece of equipment. Enjoy it, let it break in. Get to know it. Many people lust after such a piece of hardware and could never afford it. It is a piece you could easily keep for twenty or thirty years and be proud of owning. Given what you have said about your equipment, this is the highest performance piece. So, if it doesn’t blow you away, then over time as you upgrade other pieces you will realize it’s potential. 
Great decision. Enjoy.
