Burson Conductor - DAC/amp successor to the HA-160D - Page 62

post #916 of 1811
Yoga - I'm envious of your Timekeeper :-)
I use Burson's first power amp (PP-100) with Gallo Stradas (87db) with their TR-3 sub. Using Audirvana, I've been pretty thrilled with the sound.. but always wonder how I can make it that little better.

Bugger about the hiss. I had a similar problem with the HA-160D. (Using shielded ICs didn't eliminate it).
But that hasnt been an issue with the Conductor. (I only hear the faintest hiss when the volume is on full on high gain mode (no music playing, obviously))
Hope Team Burson come through with a fix for you.

If you haven't Audirvana 1.5.5+ (now 1.5.7), I suggest you give it a whirl :-)

True, but the vast difference I hear comes mostly from Chord DAC64.

Burn in did help some closing the gap between the two but still, I just can't shake off that feeling that one sounds like hi-fi and another, while doesn't sound bad at all, mid-fi at best.

Next up, lining it up against my office setup - Stello DA100 (AKM based) with Headamp GLite with DPS. Hope Burson outruns this one as this is what it was supposed to replace.

I understand.  However, that's the amp letting the DAC do it's things and staying out the way - Just saying..:biggrin:

It's an excellent piece of kit. Powers the KEFs wonderfully!

The guys at Burson are on the case, already sent me a couple of things to try.

 

There's no hiss at all with the Conductor (via LCD-2s or active monitors), it's only when the Conductor and the Timekeeper are connected via RCA. I pull the RCA cables out - no noise whatsoever. I have some better quality (shielded) cables on the way to me, hopefully that will fix it.

 

I already own Fidelia, but funny you should say that, I purchased Audirvana Plus quite literally seconds before viewing this post :¬)

SL 1793 pcm dac came in today. I think I much prefer it over the ESS saber chip, even with HD 800s, solely for the reason of no clicking when switching audio sources in coaxial mode! :beerchug:

No clicking... Now why didn't Dan tell me that smily_headphones1.gif

I didn't notice that. I will test it as soon as I have some time.

Interesting, even M2Tech HiFace2 sounds like a definite improvement over Conductor native USB.

Flipping between them back and forth right now, both with iUSB Power to minimize noise from PC.

Kind of surprising, is Tenor that bad?

Apparently so. I use this:

Absolute bargain.

I actually like the mechanical clicking sound from the unit, it doesn't happen very often, and doesn't come through the phones. It reassures me that something has physically changed when the bit rate changes:).

post #926 of 1811

Doesn't bother me either :¬)

post #927 of 1811

Has anybody compared straight optical vs any of the USB SPDIF converters?

 

I use optical output from my laptop.

Here's a snippet from an email response I received from a Burson representative when contacting them about the constant clicking.

1. This protection rely is only unique to the ESS9018 DAC chip circuit, we also offer a different DAC PCB which uses a different DAC chip and it does not require the rely as you see here: http://bursonaudio.com/1793DAC_PCB.htm
 
2. If you send back your DAC PCB we can manually remove the relay for you on the PCB. That way it will not that the clicking sound any more (we can do this for you free of charge but you will need to cover the basic postage). But it does mean if there is any noise comes from the input end you may hear it from the output. 

 

I'm very much enjoying the 1793 PCB because the clicking was quite irritating to me personally. Since I have switched out the chips, I may send the Saber DAC back to have the 'clicking' protection removed.

I'm curious how many (if any at all) owners of the Conductor/Solist with the stepped attenuator have experienced the below issue. I "borrowed" a conductor from the cable company, and this issue was prominent:

 

 

The Burson comes with a discrete volume attenuator which in theory is a mechanical switch with 24 different stops, all linked to a different value resistor. Stepped attenuators are agreed by the audiophile community to provide a better quality signal transfer path compared to standard sweeping-taper potentiometers.

When I compared the Soloist to the HA-160D which is about one year old, there was a problem in the volume control where everytime you move the position of the switch, there would be a loud “pop” noise that’s audible on the headphones. Not very pleasant, and my friend the owner told me that the pop got louder as the amp ages. The first thing I thought of is “bad contacts”. So I took a can of electronic contact cleaner, specially developed for cleaning electrical signal contacts, and I sprayed the attenuator unit with it. Afterwards the pop disappeared completely.

No real clicking from the attenuator that is audible through the phones.
