Quote: Aune T1. Spec says line out: 2V rsm and headphone amp maximum says 300 ohm - 150MW. Read somewhere that Beyer DT880-600 needs 43 mW at 600 ohms to hit 110 dB which is 5 V RMS. Thus the question.

Ordered 600 ohm version. My HPamp is rated 2vrsm. Is it enough to drive? It has 16db gaun.

Quote: Default setting is 16Db and picture in manual is inaccurate, right? To set set zero gain, I need to pull both switches opposite direction?

Quote: DT880 that is then. Thanks.

Thinking about headphone upgrade. What do you think would be ideal with T1? 32, 250 or 600ohm?

Quote: Look at the picture, plug is actually in my unit at least, the proper euro plug, Its already plugged in standard euro-socket and T1 is rocking.   I've seen the "chinese re-imagination fo euro plug" on my chinese android tablet, that does not fit anywhere...  

Using external 24bit DAC + foobar2000 + wasapi as described in OP. WASAPI (event mode, buffer lenght 510ms, 24-bit output). My windows volume control slider still seem to work. Am I doing something wrong? Or am I set for good?

  T1 finally arrived. Ebay shop, amp_universe from GB, included euro power plug, That was a big suprise and a nice bonus. I was prepared to hook it up with travel adapter, no need now! Let the sounds begin with Electro Harmonix 6922 .     Windows7 installed driver automatically and I...

Quote: JANs that Uraltone have in stock are same as these:   http://www.boiaudioworks.com/6922JANNOS   "Please note that these tubes can be microphonic and may not be suitable for use in phono stage. We recommend 6922EH tubes for low microphony requirement."   or these  ...

Based on quick search, I guess my JAN Philips is Sylvania tube.

Quote:   JAN 6922. 8713 AEX. Philips ECG. 34167 USA. I'll come back with sound preview, once the Aune arrives. I was expecting it today, but no luck so far.

Quote:   Here you go. PCC189/7ES8 and I guess patch number 50402. That's it, could not see anything else.

Quote: Only review I have seen is this.   http://www.headfonia.com/schitty-magni-and-modi/   Based on discussions it generated, it seems to be, how should i put it, controversial.

Quote: Answer was no, but I grabbed, I guess standard, Ultron PCC189 and JAN Phillips ECC88. 

Quote: Seriously, I have read all 122 pages. There's lots of info, sometimes contradicting info . After a while, ECC88, PCC88, PCC189, 6DJ8, 6N1P, 6N23P, etc. started to sound the same and I'll got confused. I already admitted that I jumped the gun with 6N1P. So what else do you want?  ...

Quote: I pressed the "buy" button, before I saw the comments about 6N23P is better. So, that ship sailed ...   I read that "PCC189 has a 7,6V serial connection heater and is a variable mu valve for regulated tuner inputs. If used in line level amps, it will produce lots of odd harmonic...

After cyrllic latin converstation try-outs, I ended buying 6N1P-EB Voskhod (rocket logo) tubes with OTK-1 marking from the '70s. I guess these are 6H1N-EV in cyrllic, but I'm not sure anymore ...   "E" military standard (up to 5000 hours and more) "B" aka "V" stands for improved Tubes...

Quote: Never mind. It seems that the cyrillic letter "H" is pronounced "en", so is transliterated as both "h" and "n", so 6n23p = 6h23n. All US sellers use "H" and all Russian sellers use "N". Anyway, spec is little different.

Quote: Tried search, but I did not see any definite answers. These 6N1P, 6N1PVI, 6N1PEV & 6N1P-EB types are widely available at low price. I noticed that spec sheet is little bit different than 6DJ8/ECC88 standard and I saw some mentionings that "pre-amp only applications".   So, my...

Quote:  Top post. Thank you, Salvatore.

My mind was set to purchase a Fostex HP-A3, but then this black horse called Aune T1 grabbed my attention. Should I save 150 bucks for tube rolling and go with the Aune or stick with my original plan. Any toughts?   Usage: PC only with USB. HP: Grado-SR80i (& possibly Klipsch Image X10 IEMS)

I pulled the trigger on X10's on Amazon offer. Should get those puppies tomorrow.

Thanks bbop. I wish my company sends me to back to Austin someday. I agree, its much nicer city What comes to All Things music at least. Anyways, I found SweetSpot and Grado's I was Looking for.
