Thanks, i guess im good as i hear literally nothing when I do this.

Also, I don't know how a power supply could be 'faster'. Electricity flows at a set speed.

By faster he probably meant transient response, the ability of an amp to start and stop a sine wave or signal immediately, or as fast as physically/electrically possible, thereby ensuring fidelity to the transient surges of the original music.

I've been trying to contact Dennis or Alex at Burson via email but keep getting the following from the MAILER-DAEMON at Yahoo:

 

<info@bursonaudio.com>:

550 without authentication.
Giving up on 198.136.54.104.

 

I've never had this problem previously in emailing them from my Yahoo account which hasn't changed.  Is anyone else experiencing the same problem??

Thanks phototristan.  Much appreciated!

Hi Solude, and fellow Conductor enthusiasts,

 

I assumed the Burson was pure class A. Is there any chance you could explain to a layman what you mean by Class A bias being increased?

 

Does the Burson go into A/B mode under certain conditions? If so what are such conditions, and what are the effects on sound performance?

 

R'gards.

post #607 of 1834

We have no hard numbers, just scope measurements and anecdotal evidence.  One it's pretty safe to assume it is class A to the output devices since prior to that, we're talking tiny current numbers.  The output however is speced at 4W into 16ohm but it runs fairly cold.  The benefit of bias is to remove harmonics, reproduce the entire wave and not just the top half etc.  Ideally you want the bias to be in around twice what the amp will ever be called upon to deliver.  So in the case of the Burson, it's probably safe to say it's pure class A for high impedance headphones and not for low impedance.  The devices they use on the output can deliver way more current than the power supply could feed so other than more heat I see no reason not to raise it to a level the power supply can still handle.  At least to the point where the case is very warm.  Then you would know it was pure class A even into orthos.

Thanks for the explanation Solude:)

Pass Labs has a great write up on it if you want more detail and pictures to visualize it.

Thanks again, interesting reading.

I love the smell of Hi-Fi equipment in the morning. Conductor arrived today. I would like to express my gratitude to the all of contributors in this thread and the Soloist thread. I've been lurking for a while and reading your experiences (positive and negative) encouraged me to take a leap of faith. 

 

 

Been playing constantly burning in (warming up) and listening. I purchased its used at a pretty good price considering it is only a couple of weeks old. I am very impressed with the sonic improvement in my system thus far. Not too sure how much use it has seen from the previous owner, so I don't know if I should expect much change in sound over time. I'll treat it as though it is new and keep it running, but suffice it to say that I won't be at all disappointed if it is currently running at its full potential.

 

I will endeavour to post some impressions of it with my other gear soon (I'm a noob audiophile, so don't expect too much), however I first need to do some trouble-shooting.

 

I can hear electrical interference between songs an during quire passage (approx -50db). There is also an issue with Foobar - WASAPI freezing up. DS works fine though.

If you're hearing noise between songs, you may have a problem as it should be dead quiet. If you are using USB, did you install the driver?

Hi,

 

The A/C noise was due to being plugged into a board with other equipment. I foolishly paid lip service to the point in the manual stating that it should be plugged into its own power point.

 

Now its sorted I can only hear my tinnitus between tracks and during quiet passages:)
 

Cheers

post #614 of 1834

Hi folks,

 

I am wondering what volume/ gain position people are using with the soloist/ conductor and LDC-2/3, and does anybody know the approximate SPL at those positions when tracks are at -0 db?

 

I'm unsure as to what is a safe listening level as this pairing sounds fantastic and is calling for more volume. Would 12 O'clock on low gain exceed safe levels. I don't want my tinnitus to get any worse.

 

Cheers.

post #615 of 1834

I used low gain, roughly 11 o'clock, which was 80dB into the ear.
