Next up is trying 10 or so different 6SN7's I have laying around with an adapter I have.


Listen guy..we can't afford you..you keep finding tubes and we keep buying...LOL. I though the two hole mullard was the winner ?

post #3857 of 5982

lwrs10, sry if I`m skeptic but you are doing all this compare too fast and without proper analytical listening as I can see. Now Valvo ECC85 is winner - by what? 

Please pick some out, take some time, choose lossless music from different genres and start comparing. Soundstage size, imaging, bass, mids, highs, transparency, separation etc.

Make sure Amperex 7308 is one main competitor, since it`s been most recommended high-end tube for Aune T1, especially in terms of "holographic" sound. 

I could also run through my tubes again fast and I`m sure with certain music genre (rock/metal for example) some tubes sound better than my top tubes. But is it better with other genres? And then there`s setup differences etc. 

It`s good to know that there are many "new" types to try but I won`t rush into buying anything you say is better because I haven`t seen any analytical comparing by you. It`s like I suggested Amperex 6GM8 to acrorob but he found GE 6GM8 much better for him. Don`t take this bad way, just something to think about and how to be more informative to other members.

These are my initial impressions. Simple as that. After I get a group of the ones I liked the most after a couple songs, then they will be analysed deeper. I have hundreds of hours with my 7308 already, so I have been comparing everything it it.

 

 

This is how I do things. I can usually immediately hear the differences between tube types/brands. Some more than others. I does not take me hours to decide on any piece of audio gear ever. 1-2 of my favorite songs is all it usually takes. I built my own tube amps in my main system, and have been through enough tubes in that. When you have a setup that is very resolving it does not take hours and hours and 20 of your favorite albums to decide.

 

 

Now all that being said, I have different tubes for different styles of music too. 

 

Metal: A nice crunchy very forward tube, like the Russian 6N1P or the 6N23

 

Normal Rock: A very detailed slightly warm tube. I like the Amperex 7308 here. 

 

Jazz: A detailed, neutral, wide, and deep soundstage tube. A NOS Genelex Gold Lion fit this bill.

 

 

 

This is how I usually use my Aune. Now that these ECC85's have come to light, I get to redo all of my findings. Fine with me, means i get to listen to more music.

 

 

 

Also, with a pile of 300 or so tubes here to try, where would I get the time?

 

 

 

I am a busy bee already with these new tubes.....

 

 

 

 

and I just found these.....Harmon Kardon labelled ECC85's by Amperex, but made in England? Know what that means???

300 tubes..yeah..someone married the tube fairy...LOL

 

Good deal.

 

Actually have 4 tubes inbound. A Sylvania and a Mullard ECC88 and a Siemens GE and a Mullard ECC85.

 

Like you I immediately pick up differences. I have some key tracks I play to test voice, depth, bass, mids, etc. sometimes it is harder than others if they are close and requires more in-depth (always do anyway) but sometimes it is extremely obvious if they don't really pass my initial test (like the VOKSHOD 6N23P which were really 6H23N)

post #3860 of 5982

I did not mean that you have to take hours & days to compare but just... don`t rush ;) Will wait for more specific impressions about your new findings.

 

It`s about taste also. For example, with metal music, foward sounding tube like 6N23P doesn`t like at all for me. Amperex OG 6DJ8 GAC & Ultron SQ PCC189 way better! Actually this - "A very detailed slightly warm tube. I like the Amperex 7308 here." fits for those tubes & my taste with metal/rock/progressive/jazz. Those two tubes have middle-sized soundstage, slightly smoothed highs, great bass & mids. Kind of sweetspot for me for those genres.

The top 20 of all these tubes will get a very detailed write up for you to decide from. I will not concentrate on what music I like them with, but will be about how it sounds to me. 

post #3862 of 5982

Ok. Do your impressions as you like. My method is usually like this - 1 song from at least 3-4 main different genres like EDM, rock/metal, jazz, classical - that way it would be more useful to everybody.

And some songs are chosen specially for detecting soundstage size and imaging. That way I can give more accurate impressions for ppl with different music taste, though, my perspective is also subjective and setup different.

Anyway, thanks for testing those "new" type tubes and keep us updated! ;)

Interesting. I think 7308 is perfect for jazz.

I like his style. Discard the bad tubes and save the clearly better ones for more detailed review. Hasty impressions are one thing, but we're still waiting for you to do that summary review of your tubes. That would, no doubt, be the king of all tube reviews around here ;)

That`s the way to do it!

I also have to revisit my tube review again sometime, but don`t know when because I have too many great sounding tubes and finding differences + judging by genre takes time that I just don`t have ;(

But still, I know my favs with my setup with different genres and I dare to recommend them to others.

That would be awesome review!

Those should be very rare I guess! Haven`t even seen any harman/kardon labeled tubes ;D

Well one of those Harmon Kardon ECC85's is bad.....damn. 

 

 

 

Lets see what type of reaction this gets......

 

post #3866 of 5982

This seems to be getting endless ;D Damn that little black money sucking box! ;D

Did you tested those types by yourself or was it just assumption by tube requirements? Asking because then I know if I will add them to "blue" tube list ;)

CV5358, M3624, CV4108, CV5331, CV5464, CV5472, CV8065, CV9838, CV10320, CV10403

6FW8, ECC85 6AQ8, PCC85 & 9AQ8->some may sound distorted due to underpowered 9V heater,

6BQ7A, 6BZ7, 6BS8, 6BK7B->some may not work probably due to "too high" mA current draw.

 

CV tube types cross-reference: http://www.audiotubes.com/cv2000.htm

Chinese tubes cross-reference: http://www.audiotubes.com/chinese.htm

 

Tubes marked in green are tube types that I personally have tried with Aune T1 and seem to work with no problems.

Tubes marked in blue are tube types that other users have tried with Aune T1 and seem to work with no problems.

Tubes marked in orange are tube types that have been tested by some users but some of them did not work.

I've been lurking and reading and can't seem to find the answer to this:

 

Does the volume knob on top control the RCA line output as well as the headphone output?

post #3868 of 5982

Well I'll be damned.....a 6SN7 actually WORKS!

It does not control line out, only headphone jack out.

LOL! ;D But how does it sound? Good? Can you give us schematic for building that adapter? ;P

Do you accidentally have one of those laying around? -> http://www.ebay.co.uk/itm/Strong-RCA-Black-Plate-D-Getter-with-Foil-Strip-6BQ7A-Tube-/111035867145?pt=Vintage_Electronics_R2&hash=item19da40e009
 

Those seem very interesting because of construction.

Well the first 2 6SN7's honestly sounded kinda dull. They were Sylvania 6SN7GTB. Using a RCA ruby base 6SN7GT and now we are on the right track. Better, but there might be a bit of harshness on the top end. But this is also a NOS tube, so it might need some break-in.
