Great.

 

I will have more impressions to go by.

Also would be very interested in hearing about tur-06 vs tu-05. Im guessing the tu-05 should be better though right? Because it is the totl model?

I wrote a review of both units a few months back :-

 

TU-05b: http://www.head-fi.org/products/analog-squared-paper-tu-05b/reviews/9072

TUR-06: http://www.head-fi.org/products/analog-squared-paper-tur-06-portable-hybrid-tube-amp/reviews/9073

 

Different strokes for different folks I'd personally say. I actually bought the TUR-06 myself in the end. The reason was that at least with the demo units I had (can't remember which tubes were used) the TUR-06 was somewhat a more fun signature whereas the TU-05b was more a "purist" audiophile tube amp. The TUR-06 is a hybrid and the TU-05b a SET amp, but both Class A if memory serves me correctly.

 

In the end, as good as the TU-05b, I couldn't see myself on-the-move with it unlike some of the other owners here. So I went for the lighter/smaller transportable TUR-06.

 

It's a pity I had to return the TU-05b though. Currawong was asking if I could compare it against the WA7 or StudioSix.

Guys,

 

Today, at a French "Audio tuning specialist" 's place, I tested a very interesting damping material.from FOQ.JP.

 

 

 

To test it, I just placed one sheet of it under my TU-05 and one sheet above my TU-05, and... it worked immediatly: more clarity, less micro noise....

 

So I bought 2 bags of it (4 sheets) it and will fix it at several strategic location inside (on the transformer, on the battery...) and outside my TU-05. 

 

It is 1 mm self adhesive sheets of damping materials. And the most interesting point, as opposed to the other "heavy solutions", this one do not restrict the portability of our amp that can still be carried everywhere in its nice leather bag.

 

I will keept you informed :-)

 

Also, you should read this very interesting article about "damping, vibrations" (& vibration absorbing platform)

AnakChan,

 
Unfortunately, NO.
 
I am in no hurry, so will just wait on it, and Shikada-san seems real busy............

bmichels,
 
This is very interesting, do you know what the damping material is made of? At first I thought that it might be sorbothane sheets, but the company website says that it's an "Organic polymer hybrid system" which sounds very mysterious.

My modest collection.... finally organized  :D.  Left box = voltage gain stage - Right box = Power stage

 

OK OK I know: I am safe on the Philips DL92 side....

well sorted!
post #2350 of 3470
A lot of things arrived today:

Tube sockets and two pcb's:



This small boards are lithium ion battery charger and protection circuit boards for larger lithium ion cells:



Tesla 1F33 - DF96:





Cifte 3A4 - DL93:



Philips DF92:



Philips DL92:



These pins definetely need some cleaning:

I see that the building is not far away...

 

About the Galaxy Note 22, HOW do you get around the Android's 16/44 limitation ???   with the stock player/kernel, everything is down-sampled to 16 bits when coming out of the Samsung through USB !!!  

post #2352 of 3470

thank you for informing me about this limitation ! will try my best to find a solution!

I hadn't realised this was the case but apparently so.  The LG G2 has a Wolfson WM5110 DAC which is capable of 24 bit / 192 kHz. It looks like a terrific phone but the deal breaker for me is that it doesn't have a card slot for additional memory. It beats me why so many manufacturers do this.

Well, it is much more complex than it looks:  Android is almost as stupid as Apple on this with their "frustrating limitations":  The LG G2 can internaly play 24/192 through it's internal DAC/AMP, but... it will not allow 24/192 output to an external DAC through USB. It downsample it !   (apparently in the Android world, only ONE software is able to play & output 24/192 out of the phone : "recorder pro".  But, as it's name tells, it is not a dedicated player, but instead a recording software, so the music file management is close to ZERO: all it can do is play a file or a directory) :-(((

 

 

The lengh of this thread "Android Phone and USB DAC" tell the complexity : 211pages today

So I have about twenty five hours on the Ken Rad 3S4 and Raytheon 1U4's now. Both Mil-Spec from the mid 1940's, both date match and matched technically as well.

They have opened up nicely and have been deadly silent from day one. What can I say about them? Well, I think the best thing I can say is that I have simply forgotten to think about what are their strong points as I have simply been immersed in music!

They excel at everything, Bass, rich, deep, tight. Mids, creamy, detailed and atmospheric. Treble, extended, crisp,detailed, sweet and airy.

Beautiful soundstage, just right in width and depth. Instruments and vocals are easy to place and yet at the same time they feel as a whole with the performance. There is also a wonderful up and down sense with these tubes by which I mean you can feel the placement of the instruments or vocal lower or higher in the soundstage.

I have been listening a lot to two rips of CD's which are just wonderful for orchestral music. The first is an old Ted Heath recording of Glenn Miller's music and the other is James Horner's Bicentennial Man soundtrack. I just get lost in both, Horner's soundtrack is almost transcendental and these tubes make that even more so.

The Ted Heath album is the best I have heard it. Millers arrangements have never sounded better. Horns have punch and speed and yet one can hear the fruitiness of the trombones so well, rich and detailed. On Pennsylvania 6-5000 The bells which are rung were right in the center and just a little low, it felt like they were lodged in the middle of my neck!

Without a shadow of a doubt this combination of tubes is the best I have used yet and to be honest I simply see no point in changing them out again. Everything is there. They allow the amp to really shine. Just stunning tubes, I am quite taken aback actually at how good they sound and how they simply get out of the way and allow a recording to show its all!
