Audio Research LS28SE vs McIntosh C53

I would stretch to get a ar 6se, maybe a nice used one will be out there.  Always concerned about how audio research Burns tubes aggressively.  Why not A Tube preamp from McIntosh which is a lot easier on tubes?

OP,

Tube problems happen, but are rare. I now run over fifty tubes and have not had any problems for years. I had one whistle a few years ago. I just brought out my backup set and replaced one by one until the whistle disappeared. 

Tubes are outside the control of the manufacturer. And as I say, generally are very reliable. I just recommend, replacing the other couple tubes... to rest your mind... and you'll probably never experience a problem in your life. I know other folks (that own a LS28SE and other ARC) and have never had a problem. 

Just be careful with any tube electronics.  While on the surface, it seems it can be fixed at any old shop, you may be in for a long wait if something does go wrong.  My ARC ref 10 blew a tube once, took the surrounding "sacrificial" resistors with it.  TOok about 6 months to get back on its feet.  

I have heard Audio Research has reduced their backlog to less than a month. 

Although changing tubes is not a hazardous process. 

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.
