Looks like another facetious post, and then some wonder why some would sooner not visit certain head-fi forums.

I was not being facetious.

i was applauding the statement:-

Well said.

I will amend my previous post to reflect this.

Great, thanks for the info.

Have a dumb question, not very good at phrasing it so hopefully someone can understand what I'm asking..

 

How are the tubes arranged for 2 matched pairs?

A matched pair in front and a matched pair at the back?

Or, matched pairs on either side of the amp; ie, one pair on the left and another on the right?

 

Thanks in advance.

 

The amp is dual mono so one channel uses the left hand tubes, the other the right hand ones.

Because of that I decided to listen to my 009's driven by my BHSE with the volume knob at 11 o'clock, and to what I can recall, when I heard my 009's along with headfier IanG's 007's with the BHSE and not changing the volume knob, the difference between the 009's and 007's sounded a lot more than 6dB. This makes me feel that while graphs and specs might be a good thing, the only true way to know is to listen.

In the end, we can only live with our opinions based on what our ears tell us.

This does not mean that we do not need to train our ears - train our ears, not delude out brains.

 

 

 

is someone listening to Inna-Gadda_da-Vida or the Magic Flute? at 70 dB ave SPL or 90?

 

without numbers its really hard to guess if there is any transitivity in random poster's subjective remarks - learning to broadly identify musical frequency bands, SPL, knowing some psychoacoustics like Loudness curves, critical bands, masking, understanding headphone measurements, sensitivities, amp I/V constraints, system gain structure seems a lot more useful than the ~ "you got to put a sock in the 009 to sound like 007"

 

head-fi - even the high end forum should be about education for listening enjoyment - which  learning some numbers can help with

 

today the audio press is overwhelmingly serving marketing, cultivating fake consumerism, naive subjectivism, promoting "just listen" to empty your wallet

 

I don't see why any forum should want to serve up more of that, reinforce it by degninating intelligent use of objective measures, psychoacoustic, aduio technical knowledge where they do help understanding subjective audio esperience

about 4 months.  the 3rd batch is practically sold out.  there will be a few spots still available due to cancellations.  i have also ordered parts for both batches #3 and #4, so there will be a shorter wait between those.  

 

there is no 240v model but 230v is close enough.  the regulated power supply will work with the 220-240v range.

Justin, what is left for batch 3 to be finished?

Thanks, Birgir.

What the estimated ship times for batch #3 and #4?  Trying to find out what batch I can jump on.

post #2875 of 4975

I know that this question has been asked and answered long time ago in this thread, but I just cannot find the posts: assuming that one is using the BHSE one or two hours a day at the most, how long do you think that this beast may last? I would like to ask the same question for the tubes provided with the amp. Also, I do remember that someone mentioned that a part in particular might need to be replaced at some point, but I don't remember which one it is. Thank you.

High quality capacitors are rated for 10,000 hours. Well-made tubes will last a lot longer.

I am not sure whether you still keep the BHSE until the capacitors dry out...

I am sorry that I am so ignorant about “capacitors,” but I assume that they are a important parts of the amp... So it means that this may last about 15 years, assuming that I listen to it 2 hours every day, is that right? Would it be any different with a solid state amp?

that's at their maximum rated temperature, such as 85C or 105C.  as an estimate, the life will double for every 10C below this.  so if the capacitors are at 50C its going to be a lot longer.

every electrostatic amp is using electrolytic capacitors in the power supply.  so is your computer and just about every piece of equipment except recently things that have to be made very thin, like cell phones, you're going to find mostly tantalum and ceramic capacitors
