Whoa, how did you make those panels? FPE?
The red line applies to any value pot or stepped resistor attenuator. 6 dB attenuation is where the pot is halfway between two ends. The effect a 5K+5K divider, 6 dB attenuation, will have on frequency response may be seen in the blue lines for the 6 dB attenuation graphs found here . Short, low capacitance cables will introduce less than 0.2 dB roll-off at 20KHz, worst case. What is missing from this discussion is the combined effect of LC network formed by the AVC inductance and cable capacitance.
Does anyone else think that @bazelio is going for a Marty McFly on this?
@atomicbob have you ever (or know a properly measured ref) measured same cable with different make for the plugs (rca or xlr) ?
Yeah I am at precisely -22.5 dB right now. This is a slightly loud listening volume most of the time. I expect that to increase slightly once I have finished off my room treatment. At the moment, I rarely go louder than -20 dB. EDIT: Speaking of which, GIK has 20% off Acoustic Art panels until the end of April. You can turn all or almost all their panels into art panels and provide your own image or vector files.
Yup! FPE and a spreadsheet + high school math to calculate the coordinates and angles of all the tick marks. That was basically all manual inside FPE as the software isn't terribly feature rich. But it sure does give you an opportunity to create, and in the end, they ended up dead on. Every position of the AVC lands squarely on a tick mark.
I don't have the db marks, but I'm basically at 10am to 1:30pm on mine as well. 2pm or above would be pretty damn loud in my system.
you have a PM.
Looks like Nord Acoustic is about to release a TVC pre that isn’t priced out of this world https://www.nordacoustics.co.uk/single-post/2019/03/17/Nord-TVC-Pre-Amp-nearly-finished
£2K ?? No thanks. Maybe Schiit will do an AVC or TVC preamp some day so I’ll get to hear one.
Agree, it would be lovely if they could fill the gap: in general passive preamps come either at idiotic price points, or are inadequate.
My pre-amp was $1k, two decades ago. (bought by me just a few years ago for very much less). My one and only ever piece of Stereophile A-list kit!
Have a refurbishment plan. But I find that even non-audiophool gold-plated phono sockets are INR300 and it needs 22. For starters.
And the scratchy pot? eek. But my magic repair man (who was working on another of Koth Ganesh's boxes when I saw him 2 days back) says he can spray some magic liquid into that.
Unless Schiit can outsource good AVCs/TVCs from China, where the salary is much lower than US or European, I don't think you can expect the good AVC/TVC passive preamp for less than 1.5K. The high quality core is not cheap, the good winding technique is mandatory, and the salary for professional winders in US/Europe is also not cheap too. Adding the cost for case, wiring,... and profit for manufacturer, the price will go up. And trust me, unlike the pot volume (Alps) or relay stepped attenuator (like in Schiit preamp), the low cost TVC/AVC with inadequate winding technique or low quality core is unbearable
I would buy this.
Make it so Bazzy
That's a very pretty display screen. Tempted, wonder what the final price will be.
Is use of Apple remote for higher-end audio gear common these days? Guess it makes sense, the user can purchase it cheaper than it would cost Nord to OEM it.
Whole heartedly agree with you. I know my music first audio TVC is not cheap, yet I do not think it is overpriced given the BOM and the time a skilled person needs to put everything together.
A cheaper option with good quality might be:
Never heard it myself and did not consider it due to lack of European warranty.
What I cannot get my head around is why anybody would add a remote function, which introduces an active electric circuit to the passive amp, even if it is not in the path of the audio signal. Beats me. But hey the more (choices) the merrier.
When your gear is in an audio closet.
Time for your gear to come out of the closet man, it’s almost 2020 already!
I've seen Promitheus mentioned around here but has anyone actually ordered one of their products? Are they still in business and making these things? Looks like that last external reference they list is from Stereophile in 2007.
If that's the tranny from Bangkok, @MrTeaRex played with it and it gave him herpes. He can expound.
