Need a new amp

I'm a dealer for both Line Magnetic and Cary, so can perhaps help a bit. Both are very good options, although I've never heard either with Golden Ear speakers.

Obviously one is an integrated and the other mono-block amps.  Would you prefer the integrated option, or does it matter?

If you go with the amps, are you planning on keeping your current preamp?....  Or getting a new pre?

The LM would be quite bit less money, especially if you add in the cost of the preamp.

For space reasons I wouldn’t mind the integrated as long as I am not giving up too much sound. 
If I went with amps I would need to get a preamp. 

LM sounds like the way to go. 

For power amp check out Audio Mirror's 45 WATT SET monoblocks. These are awesome sounding amps and rated very conservatively, so well capable to drive your speakers. They drive my 87dB/8 ohm speakers very well.

If you are looking for new gear, you should check out the Art Audio Quartets which are a 45w 845 based mono-block.  I ran them for almost 18 months and they are brilliant.  There is a full review in Enjoy the Music that was done by Professor Michael Bump.  

They are incredible with the Conductor Preamp.  It is a great match and one I would get any day.  

I ran that combo in my home and at AXPONA and Capital Audiofest in 2019.  If it isn't clear, I am the importer which I know makes me biased but it is worth checking out coverage.  Best was in part-time audiophile from both of those shows.
