Why do you think some of the most hardcore audiophiles out there still run old CDP's and NOS DAC's that sport those old Philips or Burr Brown PCM IC's? 

 

My description of the classification I've written above isn't what you're misinterpreting, for example, either of the family of DAC's can of one or possibly more of the fitting description I've written, I didn't group ESS Sabre's as all of the above description, it can be either neutral or clinical sounding, or both. 


I agree with you on this.  If you spend big on dacs - digititus is significantly reduced...if I was on a budget though - I would track down a good nos dac.

 

Having said that - I don't think amping the LCD2s for power is a big issue with todays current crop of amps.  Get a good one and the LCD2s reward with better dacs - in big ways.  But I am firmly in the source first crowd.

No you're not wrong that's your opinion and I respect that but remember you need to back up ridiculous claims with evidence and experience you've had with both sides of the fence not just primarily one side. 

 

As regards with my previous post as well I'm not dismissing all ESS Sabre chip based DAC's as sterile, bright and lack life...no but I stated that it could be one of those adjectives I've thrown in the post that classifies the Sabre quite boldly, be it neutral sounding or bright or even both it becomes quite evident when you hear it from the transducers speakers or headphones, music source is 0's and 1's they have no attributes to attaining whether they are warm or bright sounding that is outputted by the rest of the chain of your setup, but mastering of the recording very well results whether or not it will make it enjoyable to listen to for the end user.

The true thing about most NOS is that it is not done right, no I'm not engineer but I've read white papers by leading industry engineers and designers evaluating and critisizing some of the designs other people have been following off old stuff for decades. With a bit knowledge one can gather off these days off the internet or forum you can fix and implement true non-oversampling to DAC IC's in old CDP's or DAC's. CDP's are the best platform to try it on because they are easy, cheap and give a very rewarding experience to both knowledge and joy to the music it literally sometimes put's them up on the same plane as the big boys - 4 to 5 digit priced players. 

 

One of the very few engineers that I know of that knows NOS back to front, right to left and has done it properly as well as me hearing it is Guido Tent's "Tent Labs" DAC's and his DIY CDP (not sure if he still does NOS mods though), good schit is good.

How do these specs sit with you guys?

 

Quote:
 

Analog Output

RCA Output Level: 2Vrms at 0dBFS

XLR Output Level: 4Vrms at 0dBFS(XLR:1=GND,2=HOT,3=COLD)

Frequency Response: 20Hz(+0.01dB)~20KHz(-0.03dB)

SNR: 115dB 0dBFS unweighted     117dB 0dBFS A-weighted

THD+N: 0.0006% @ 1KHz 0dBFS

Cross Talk: -125dB @ 1kHz

Headphone Output Impedance: 12ohms

 

Is that output impedance something I need to worry about - if it's purely for driving LCD-2.2?

Don't think output impedance matters so much with planars.

They are a purely resistive load, so it may not be as important as some dynamic drivers.  You probably wouldn't want an output impedance too much higher than 8 ohms however.  12 ohms is a little bit higher than you would ideally like, but it should still work reasonably well.

How well would a Schiit Magni work with these cans?  Later on I'd likely upgrade the amplification but I'm wondering if they'd be fine with this amp in the mean time.

Posted photos of my new DAC/amp unit in the LCD2 thread, but it's worth posting here, as it pairs with the LCD2.2 beautifully.

300B single ended amplifiers (speaker amplifiers not headphone) putting out 18 watts per channel sound sublime with the LCD-2's ..

.....Woah.

You're from Melbourne, aren't you ?  If ever you want to hear them, let me know ...  :beerchug:

Whoa... how are you getting 18W out of 300Bs?   They usually top out at 8W or so, IIRC.

Yes - you are right ... most amplifiers will run 300b's at around 7-9 Watts.  These amplifiers have 2 x 300b tubes per monoblock (4 in total) run in parallel.  I'm not sure that I need the extra power at all, but they sound amazing, which is all that counts !!  :L3000:

I am considering buying the lcd-2.2, and an amp to drive them. One of the amps I am looking at has a max output of 1 watt,  and the other amp has 3 watts output, according to Audeze website they suggest between 1 and 4 watts.  I am inclined to believe the 3 watt amp is a better choice as the first is only able to produce the minimum watts suggested.  does anyone have experience with amps rated at 1 watt with the lcd-2, and if so what were your impressions in regards to having enough power

 

Both amps i am looking at are tube amps, single end topology  (I refrain from posting company names as I'm not looking for biased opinions given because someone likes company A better than B)

 

Thanks for any help  :smile:

Moar watts always wins! Seriously though it just depends on the synergy, between the two. 1 watt from a Tube amp can be plenty for the LCD-2, I think they are very good with the WA7 which I think puts out around 1 watt. Have you any chance to listen to them both?

For the latecomers/unaware, I am still accepting orders for a Robinette v3 box. See details in the Robinette Box thread :)
