Audio Research preamps EXCESSIVE OPERATING COSTS

Soooo disappointing.
So you want to use in home theatre mode.  Get ready to pay up to operate.   The tubes stay on and when family uses system 10 plus hrs a day for tv and videos, the tubes burn away.  Most of the 8 tubes have life of 4000 hrs and cost $150 per tube to replace.  Over 5 years operating costs could approach $5000 or more.  And this excludes wasteful elec costs of $100 to $200 per year for bulbs running without being used.   Sooooo disappointing.


I called audio research and they confirmed all this.  Further, they lacked any sensitivity to theses issues.  Seemed kinda arrogant.  

Sooooo disappointing.

Two issues here:  I am considering a purchase.  Don’t own arc.  Next, I will explore a cheaper tube,  but I saw them from a tube seller for more than 100.   Very expensive when replacing 8 tubes.

@emergingsoul  Its unusual to have to replace all the tubes at once! Tubes have really variable service lives. Some will go a few hundred hours and others will go 20,000 hours.

I never use HT-Passthrough. W/my Bryston I hook up the Balanced connections to my Krell Showcase. W/the RCA's I connect the amp to my Luxman CL38U-SE. When I had a CJ ET-3 SE I did the same. All I had to do was hit the switch on the amp and turn on the preamp I was using. Saves on tube use.

do you share an amp between processor and stereo preamp?

Can u do this? Sounds creative.

Thanks for more info.
