I’ve just joined this forum as a result of doing some research on particular upgrades to my system. I am looking(hoping) Australian supplies of the DirectStream DAC will hold out till next Friday when my dealer has said that the spike in demand of this day has put some orders back till May 2019.! My dealer is hopeful for getting one for me by this Friday (an early Christmas Present! ;-).
In anticipation - and with additional research - it seems that BHK Pre is preamp that my system could benefit from. I’m currently running a Bel Canto Dac direct into my amplifier. I have been happy with that setup - not needing a dedicated preamp - but it appears I may be missing out!
So - I do have a question regarding the tubes and their life. I use my system in the family lounge room where it does the TV sound duty. So - the system is currently on 24 x 7 - I never turn it off … (I’m running a class D amp). Given that the BHK pre goes into a standby mode means the tubes are not powered up 24x7 but the usage with TV and music together would total to around 5 hrs a day average. Doing the maths here results in ( 5 x 7days x 52weeks) 1820 hrs/year.
And the question is based on this usage - how long before tubes are recommended to be replaced.?
Thanks all in anticipation of being a genuine PS Audio DS Dac and BHK Pre owner!
