I meant have you noticed any noticeable differences with cheap and expensive DACs when using the LF 339?

This is going to be an unpopular message but anyway:  I've meanwhile tried DACs ranging from an el cheapo -but by no means bad- ODAC, all the way to an MSB Diamond dac IV+ which I got to try for a couple of hours.  Apart from the filters that are applied and where some small differences sometimes are noticeable (on very resolving ss amps), to me they basically sound the same on the same amp.  

 

I'm sure some are theoretically better than others but any differences are mostly mathematical and beyond the threshold of audibility, especially if you then send the signal through a tube amp which even if well constructed has distortion that's at least an order of magnitude higher than a halfway decent ss amp.  Don't get me wrong, I love tubes.  But if signal fidelity is what you're looking for then you have to look at ss gear and any minute dac differences will imo be swamped by the amplifier.

 

Just my 2 cents, if someone feels a gazillion bucks DAC sounds better:  more power to them,  I'm not about to argue the point.

To me there is a difference, I can A/B out between an audioquest dragonfly and odac. The odac is better than dragonfly, more detail for the LF339

Do you think you can do this or have you actually done it under controlled circumstances when someone else (or a program) was doing the switching and gotten a statistically relevant result?  Bias can be a powerful thing.  Anyway, I'll give it a rest, discussion of double bind tests is only allowed in the sound science forum.

Please stop the BS guys :biggrin:

Of course you can hear the difference between DACS, would be bad if there were no differences

Using my audio gd fun as preamp, soundstage was more wide when using SS amp. I wanted to know how well high level preamps scaled with the LF. I tried using just my iphone connected to the LF and the soundstage was squashed, detail was not as good.

Been using the RCA JAN 6AS7G with 5693 Red Hots, waiting on more tubes to make a list and I will compare.

I'm now part of the 339 club! I've taken some pictures of the inside. Sure looks like the 2013 version to me but I purchased the 2011 version which was $100 less. Maybe I got lucky and they sent the 2013 version by mistake :D. The only problem now is that the seller forgot to include the power cables so I am unable to use it :(

I think that's a model in between actually. I don't think they ever come with power cables. Just unplug 2 other devices :biggrin:

You can just use 2pcs of cables that are used by your PC.

Ahh ok :D and I dont have 2 power cables unfortunately. Only 1

post #2516 of 3811

Listen single mono then :D

post #2517 of 3811

Never mind I found a spare one. just gotta plug it in and fire it up :D

All works well. originally there was a hiss in the right ear but I took out the tubes and cleaned the pins on the NOS RCA 6as7's and the hiss has gone :)

Enjoy, it's possible that the sound will still change a bit, new capacitors need to settle in for a couple of hours before they reach equilibrium. I wonder about the version you have, that's one of the weak spots with the LF amps; sound and build quality are very good but changelog documentation is a disaster.

As Ultrainferno said it seems to be some sort of hybrid of the 2011 and 2013 amps. I'm happy though that it has the upgraded resistors :). So far I am very happy with the sound from the RCA 6as7's and Japanese 6sj7 mesh plates though in the near future I am hoping to get 6080 graphite plates and some tung sol mesh plates to try out.
