rod Posted May 23, 2022 Report Share Posted May 23, 2022 Before I do so I want to make sure, I am going to run a blue hawaii out of my T+A PA300HV integrated amps pre outs . I want to use the T+A amp for volume control, as I can just use the remote then, am I right in thinking that it will be fine to turn the BHSE volume control to full and do this? thanks Quote Link to comment Share on other sites More sharing options...

I want to use the T+A amp for volume control, as I can just use the remote then, am I right in thinking that it will be fine to turn the BHSE volume control to full and do this? thanks Like most pre-amplifiers the blue hawaii topology is actually an attenuator followed by fixed amplification stages. (in the case of the blue hawaii totalling x1000 times gain). The amplification stages will amplify by a fixed amount regardless and independently of the blue hawaii volume control. The blue hawaii volume control simply reduces the input voltage before it is then amplified by x1000. This means any noise on the inputs will also be multiplied by 1000! if you bypass the volume control so you need a quiet pre amp and sources. One thing to be cautious of is, when you switch off anything connected to the inputs of the blue hawaii if thing being switched off creates a thump or generates a dc offset as it is shutting down the blue hawaii will be multiply it by x1000 and sent it to the headphones... THUMP! SIZZLE! So its highly recommended to have the blue hawaii volume at full attenuation before you switch anything else on or off. You can get a similar situation if you switch off a preamp before switching off the power amp in a loudspeaker setup. Other than this their should be no problems and in fact some forum members have built blue hawaiis and similar without volume controls in them.

rizena Posted February 22 Report Share Posted February 22 We got information that the price of the headamp grand cayman amplifier is 2.5 to 3 times that of bhse. And they only produce 25 pieces a year. The price is too high, so there will be few users. Quote Link to comment Share on other sites More sharing options...
audiostar Posted February 22 Report Share Posted February 22 A "high-end" amp with a build in power supply... You can buy a T2 for that kind of money. Quote Link to comment Share on other sites More sharing options...

audiostar Posted February 22 Report Share Posted February 22 Kerry? 3* 6995 = 20k, no? And I can sell you mine as well 🙂 Quote Link to comment Share on other sites More sharing options...
n_maher Posted February 22 Report Share Posted February 22 I’d trust Kerry to build a T2, sure. And I haven’t seen Justin post a price, just speculation from folks like you, but I suspect that whatever it will be priced at will be a fair approximation of how much it costs to build, how many he might be able to sell, and how much it costs to bring something like this to market. There will always be lower-cost options to boutique items like this and folks like yourself are free to make choices and build other things if they’re able. But I trust Justin more than anything to have managed the power supply requirements to the point that if he found a way to put it in one chassis I’m not worried about it being there. I’m not sure I’ve met someone more obsessed with noise floor and the ability to actually measure what he’s building. Lastly, putting quotes around high-end in your post bugs me more than anything else. Quote Link to comment Share on other sites More sharing options...
spritzer Posted February 22 Report Share Posted February 22 Yeah, it's in many ways worse to have an external PSU but let's not get some actual engineering involved here. Go buy the Woo 3ES with a 500$ opamp electrostatic amp. That is 14K$ all in and has an external PSU... well kinda as they saw the need to have the power transformers right next to the output sockets. 1 Quote Link to comment Share on other sites More sharing options...
audiostar Posted February 22 Report Share Posted February 22 Also not to forget that everything got much, much more expensive today, huge inflation, supply shortages, etc. So, to be honest, today's prices aren't comparable to what we had few years ago.

simmconn Posted February 22 Report Share Posted February 22 Since many of us would never be able to afford one, might as well take a guess what’s in it. A Megatron with SS CCS and 12AU7 cathode followers driving the DHT final stage? Quote Link to comment Share on other sites More sharing options...
