PLEASE match Advice Pass Labs X350.5 (20k) to Hovland HP-100 (2500ohms) Miss-match ???

Hey Guys - I borrowed an inexpensive tube preamp and man what a difference. My rig was screaming for tubes. So much so now I'm thinking about a tube amp also?

I know Magico needs / should have a SS amp. I only listen at normal levels. Just don't enjoy music real loud except once in a while. Do you think an ARC Reference 150 amp can drive Magico S5 Speakers proper at normal levels in my room? I just think for my taste with these speakers tubes can go a long way. Not quite sure that the ARC REF 150 is enough amp though? Thoughts? 

Loaded a few pics of my re-fit rig that is starting to take shape. Have new speaker cables coming (Cardas Clear Reflection) and new preamp (BAT 32SE) and am considering trading my Pass Labs X350.5 and a few bucks for a ARC REF 150. Thoughts?

I moved speakers out to very outside edge of carpet that can be seen in 3rd pic or so and that helped a bit. Pics make them look closer together than they really are.

UPDATE: I wanted to update my 3 threads. I appreciate very much all the feedback and help during this process. The folks on the GON are the best!

Guys my speakers were not even close to broken in. As in Brand New or very close to it.

Goodwin's told me this, they called it cold, and told me not to worry and promised me they would change dramatically.

You know how it goes though - you hear what you hear and that sort of supersedes everything else but I was trying to be patient although I'm pretty impatient by nature as my words have made pretty clear but I am learning and growing as an aphile.
 
I was inclined to be believe them as they are the Magico pro's but I was worried because I was so unhappy with how they sounded at that point.

I just didn't think when I bought a used 2 1/2 year old pair of speakers they would need Full Blown brake-in but I was wrong.

Also, I thought that even if they did need break in I doubted they would evolve so much to make that much of a difference. I hear all the talk about break in being over rated and it is more a matter of us getting used to them verse them actually changing but I also would think if anything does need break in it would be speakers with the CAP and drivers needing it.

All this said I am utterly amazed at how much they have changed. Sure I made a speaker cable change that made a nice difference but that is not where the true evolution was. I am probably around 350 hours on them or so and for a good 8 to 10 hours a day out of 24 for the last week and a half I have really given them some nice volume and some good old SPL's and given them a chance to stretch out.  

I am told the 500 - 600 range is when they really settle nicely but I am very impressed and so happy how they are evolving. now These are some very serious speakers. So much better than I thought they were going to be. PS Audio P10 landing today and BAT VK-32SE close on its heals.

As always I am going to plug my Amp via wall direct and hope to get a dedicated 20 amp set up for it and the P10 down the road in the near future but I am over the garage and getting in there means removing fire proof sheet rock etc so that may be a little while out.

Do any of you guys think it is worth plugging my Pass Labs X350.5 into the P10 or just stick to plugging into the wall.

Why did I chose the P10? Couple reasons is one many people like them and i got a such great deal on brand new one thought it was worth a try. Audiotroy told me a conditioner and another server are needed. Although I am pretty happy with my server but am open to new ideas and growing. What do you guys think?

Thanks

I'm happy to read that your patience has paid off.
I would leave the Pass Labs X350.5 plugged directly into the wall.

Thanks :) 

Beautiful system- fsmithjack
Happy Listening!
