amorphous output tx
 
Does anyone have more info on the amorphous output tx from diyhifisupply?

Also, I noticed the silk tx's listed on the site appear to be the old model. (too small in physical size and wattage to be the new ones, though the datasheet talks about the new model)
If someone from the company reads this thread.. Do you have the s325, and how much are they?

Thanks

In order to limit the number threads and keep navigation simple I've opened this thread for any comments or questions that don't fit under the other topics.
Appreciate if no other threads be opened. I will try to keep things tidy by moving non-major subjects into this thread.
thanks

We have S325 0-8-16-22 in stock. $399 for a pair

Replace Eletrolytic Output Capacitor with Obbligato Gold Premium
 
Hi Brian:

Is it possible to replace the 47uF/50V BP electrolytic Capacitor in my SACD player with Obbligato Gold Premium 47uF/400V? I'm using Blackgate NX 47uF in Super E-Cap config, just want to try out can film cap fit the job here!

Replace Eletrolytic Output Capacitor with Obbligato Gold Premium
 
Hi Brian:

Is it possible to replace the 47uF/50V BiPolar electrolytic Capacitor in my SACD player with Obbligato Gold Premium 47uF/400V? I'm using Blackgate NX 47uF in Super E-Cap config, just want to try out can film cap fit the job here!

Also if I put 2 obbligato gold premium in parallel but in difference orientation like blackgate Super E-cap configuration, will I get any sonic benefit?

Hi,

Let me answer this on Brian's behalf.

In principle - yes. However, the Obbligato capacitors are physically much larger and may be a challenge to fit.

Also, to be honest, a value of 47uF is overkill. If the input impedance of your Amplifier/Preamplifier is for example 10Kohm a coupling capacitor of 2.2uF is sufficient ( ~ 7hz -3dB point). So 47uF can support the same LF extension for a 500 Ohm load, which may not be needed in your case.

From experience, small value & size (Film) capacitors have small sonic problems, big ones have big problems.

However with electrolytic capacitors a value of as much as 100 times the minimum can be beneficial, as they are subject to electrochemical processes which cause audible (and measurable) distortion, which seems to reduce with larger values and has been shown to be lower in certain audio grade capacitors (Elna Cerafine & Elna Silmic) compared to standard units of the same value.

We have not tried this, but based on the construction of the Obbligato Capacitors I tend to doubt it.

In closing I would suggest to try the smallest value capacitor that will give sufficient low frequency response for your actual Amplifier/Preamplifier. With a 4.7uF Capacitor you are fine for loads down to 5KOhm, which is as low as I would sensibly expect, so I would recommend this unless you have really good reason's why a larger value is needed.

Kind regards Thorsten

Thanks Thorsten, the Value of 47uF is the original size installed in the player.

I think it's ok for my player to fit a gigantic 47uF/250V cap with a metal case, just want to try out the sound of film cap instead of Electrolytic.

This is kind of standard as value (or slightly larger), but does not mean such a large value is needed.

Sure, your call, it has just been my experience that the smaller value film capacitors tend to sound better (more open, better 3d space, better tone) than large ones, if they can be used (eg. value is large enough).

Kind regards Thorsten

Thanks Thorsten, maybe I can try the experiment start with 4.7uF and 10uF first, If I found the sound is great, I still have room to put one more pair in parallel!

If they will fit I would certainly give them a try. I was running the BG caps in the Super E configuration in my NOS DAC and replaced them with film caps after hearing a friends' identical unit with film output caps. Huge difference even with the Super E caps.
