Audio Research LS28SE vs McIntosh C53

ghdprentice, thank you for your very informative response. I have had McIntosh preamps although the last 3 were pre-pro. I have had 3 AR pre amps now and I do really like the LS28SE currently in my system. A recent bout with tube failure at 1900 hours caused some frustration in pinpointing the problem and seeking the resolution, which at AR’s advice was to replace 2 of the tubes and if not resolved to replace the other 2. 
And I am sure that this is probably a character flaw, but every now and then I think I hear the problem. Which makes me think must I replace more tube, I only use these from AR, but the expense concern plays a weighted factor. 
So the question pops in my mind, maybe simplify, and return to solid state. I don’t have to go with McIntosh, but at my age and being retired, long term solutions play a huge part. Preferably I would keep my system as is and use the money on other ideas I have. 
but your advice is good, I need to to the dealer where I  purchases my speakers, Sonus Faber, as they are a McIntosh dealer as well. He does push the Simm products, how ever with tariffs I think that has escalated the investment. 
 

thanks again

Yes-ura-pirate, thanks for your advice and yes I do plan to listen to the Mac before I decide. Or any other brand that pops up as a candidate for the change.

Jallan, I had no idea that ARC was planning to re-enter the SS market. Yes I would really want to hear one. Have you heard of any release dates?

eurorack, I realize that I will be entering into a new sound overall. My real concern is how different. I picked McIntosh as a primary candidate because of past experience, that I have 2 McAmps now, and their build quality. Provided that their quality has not been compromised by the acquisition by Bose. Which to my understanding Bose has made some personnel changes but product has been hands off up to now at least.

as mentioned I would consider other brands, but am not as familiar with products as I used to be. But I will say from a bad experience, I have ruled out Ayre. Not really interested in Bryston either. I do think they build a solid piece but last time I listened they seemed to sterile and lacking emotion. 
 

One other note, 90% of my listening is classic rock, some blues, some jazz and very little classical/orchestral and no c&w. 
 

thank you everyone that has responded so far

I realize that tubes are not prone to defect, however they can fail. Just as transistors can fail and the cure for a failed tube is much easier than that of a failed transistor or cap. But it is still a possibility of change that I am drawn to investigate. I may or may-not make the change, but it is still something I may decide to do. I have received some great advice and food for thought here. 
One thing I haven’t seen is suggestions for other solid state pre-amps that should be considered. I actually find that reassuring that if I do make the change, that McIntosh will be my consideration. As far as changing to a McIntosh Tube pre is not an option for me. I will just stay with my LS28SE if that is the case. 
now I do have another question that comes to mind, I was told by a well known tube dealer that I should be changing the 6H30 tubes at 2000 hours not 4000 as ARC recommends. I kind of figured, hmmm a tube dealer recommends me buying tubes twice as frequently than before. So I’d be curious what you guys think.
