Music Server/Player for NOS R2R DAC
jdavis37  Music Server/Player for NOS R2R DAC Does your dac have AES/EBU digital input, if so make sure your server has AES/EBU output, far better they say than using spdif rca.Cheers George 
Aurender N10 - Sound quality performance is erratic
JA's comments apply only to the A10 which has its own dac section. Correct, my bad, just saw Aurender and 10 and flashed back to this hobbling Aurender did on this unit..Cheers George 
Is preamp's headphone output as good as "true" output?
chrisbrewster The front panel of my adcom GTP-500 II preamp has a headphone output that has no volume control, so I’m wondering if I could send that signal to my computer for the conversion to digital. On the rear panel (if I go to the trouble... 
Aurender N10 - Sound quality performance is erratic
If you read the Stereophile review of this unit, it seem to do a little trickery to anything that’s not MQA related, JA exposed it and I commented on it in the comments.https://www.stereophile.com/content/aurender-a10-network-music-playerserver" ... 
Accuphase Vs Parasound
adn_abdat Also have a look at the new John Curl designed Parasound Hint 6 Halo Integrated, being Bi-polar and not mosfet like the E-560 it should be able to drive nastier speaker impedance loads should you ever need it. And as a big bonus, it h... 
Line Magnetic 508ia and the Elusive 805 Tube
I found the NOS 805's better than today’s expensive re-makes.A tube guru told me the reason why is because the materials used in the old tubes were very toxic EG: Nickle ect, which aren’t allowed in today’s made onesCheers George 
Line Magnetic 508ia and the Elusive 805 Tube
has tried rolling the 805 tube, what were your results, and--most importantly--where did you track them down? At the time ebay and retro tube stores/wreckers that specialize in old tube radio transmitters.The best sounding 805 I had was by far th... 
My Amp is Broken - Not Sure What to Do - Any Recommendations?
grannyring4,348 posts10-14-2018 1:28pmA good tech/modifier could fix this amp. You simply need a new way of handling the protection circuit in your amp. No way your amp is now trash. Are you near any good tube amp builders or techs? +1 This is ... 
Cary 805 questions; with Sonus Faber Amati Homage speakers
George I think we are ships passing in the night. I will stop trying to rephrase my question. Thanks for your time anyway! Well maybe the only way is to ask me if I believe in voodoo, the answer I’m proud to say is an emphatic no! I know you wish... 
Preamp Advice for my System
richmos OP The Ref1000 monbocks are: " The input impedance was to specification at low and middle frequencies, at 200k ohms balanced and 100k ohms unbalanced. These figures dropped to 160k and 58k ohms at 20kHz, respectively, but these are sti... 
Horns: Why don't they image well?
+1 Jim , exactly what I found, even with today's horn loaded speakers, like Avantguard range ect, a wall of sound I call it without much pinpoint image placement and depth perception, like all the esl's, planers and ribbons you mentioned can do. S... 
Passive or Active Pre- Amp for Nuforce STA200
George, thanks for your input. Since I am a neophyte; what is the input impedance of a typical power amp? There "was" an industry standard of 47or51kohm I wish they stuck to it, and many tube amps went higher at 100kohm, Rogue use 1megohm!!! All ... 
More discrete R2R dac's, Cyan 3 different models.
No, but there's glowing reviews of other models. I own a R2R Multibit (chip) Linn CD12, and think so far for me it's the only way of doing PCM (Redbook) conversion properly, but it's not discrete R2R Multibit as these are. I believe there's the op... 
Unity Gain Tube Buffer - Choosing the Right Location
The output impedance is 100 ohms from the metrum and the input impedance of the red dragon is 50kohms. I currently a using a schiit sys which is a passive resistive volume control. You don’t have any impedance mismatch, the Metrum is great at 10... 
Passive or Active Pre- Amp for Nuforce STA200
coachpoconnor The  Nuforce STA200 is 51kohm input impedance, which will be a good match for passive pramps, and it's input sensitivity is 0.45v for full output power, so it definately doesn't need an active preamps with even more gain. The Sag...
