So I went and ordered the Cavalli LAu this morning. Hopefully I will now have one of the best amps for my (C)IEMs and one for my Cans.....bigsmile_face.gif

Why did you choose the LAu instead of the Liquid Glass ? Do you believe it sound better ?
No tube rolling With the LAu !!! :-((

Hello

 

Not liking hassle........and just wanting things to work, without doubt in my mind as to whether this tube will sound better than that one, the LAu seemed the obvious choice for me.

 

Plus I was highly recommended that the LAu was the Amp .....

Thanks GG.   so I will first concentrate on testing the RFT DF97 (pins 4 & 5 connected ?)/ Philips DL92 combo and then I will try to find some PHILCO 1S4.  (any idea where to find some ?)

 

 

 

Question: Are the Mulard DF96 a good tube ?  worth testing ?

Thanks Ian

 

I was fortunate that there was a canceled order on the first batch run...I jumped on it when informed, and see that orders are now closed on the LAu run, until the next batch in November.

 

But honestly, the TU-05 is really quite sensational sounding with (C)IEMs as sent out by Shikada-san. 

 

I applaud what GG is doing with his, and wished I had such technical ability. 

 

thanks a lot, i feel really honored!

i think all the mullard tubes are worth testing. regarding the philco 1s4, i bought all available tubes (and much more other 1s4), also i have just looked for additional ones but found nothing (i damaged one of the philco tubes trying to bend the pins into their correct position).

 

i also have listened to the mullard dl92 after three hours of burn-in, but i found them rather 2dimensional sounding.

 

the philco tubes are from about 1950 and made by sylvania, so you could try some sylvania 1s4, but don't forget to cut pin 1!

i would be happy to get some feedback on my modifications i am planning to implement and have posted here as i may have forgotten something or there are other ideas worth to provide.

post #1989 of 3496
GG, three hours in my experience is no where near enough time to get the full idea of any tube. Allow a good twenty hours and then you start to get an idea of what the tube is capable of truly. I found that especially so with my mullards.

First, I believe that the vu meter mod should de done. It looks gorgeous !  just make sure that this has no consequences on the clarity of the signal...

 

Powersafe mode : I see that there are some long cables (to go to the Switch and to come back) coming from the pins of the tube. Are you sure that this do not alter tha sound ? 

 

DAC ?  Will it be internal ?  Which one have you choosed ?

 

Question: what is the benefit of having balanced input and balanced output is the internal design is NOT balanced ??

 

Anyway,  I love the project and believe that all the rest is for me very good ideas, including  the XLR headphone plugs that offer better contacts and rigidity than a JACK.

yes, i know, but with your post you gave me the idea to let the tubes burn in while i'm at work, so in the evening i can listen to music and not using the time to burn in new tubes while listening.

 

will start tomorrow morning doing this with the mullard df91 - mullard dl92 combo.

post #1992 of 3496
Hmm, every single thing I have ever read about tube amps advises not to do that GG. I would caution against that and perhaps instead focus on one set for twenty hours of normal usage.
post #1993 of 3496

i mean normal usage, setting the player to repeat mode, connecting the headphone and just let the music play the whole day, whenever i speak of burn-in i use this procedure, not only turning the amp on.

after damaging one of the philco 1s4 tubes i tested different dl92 and 1s4 tubes and found the rca 1s4 a great sounding alternative!

YOU MEAN :   RFT DF97 + RCA 1s4  COMBO ?   As good as  RFT DF97 +  philco 1s4 ?  different sound signature ?
