Very much looking forward to your impressions.

On another note, twenty hours on the Phillips now and they are just sublime, quiet tubes to my ears ( these are the Canadian ones)

is this portable system or desktop system?  Do you have pictures?

Ian, I bought the DF96 Philips from the US seller.  Do you believe that they will be the same as yours bought from the Canadian seller ?

 

With what tube did you paired the philips for those "sublime" 20 hours ?

This is a video my friend Peter (AVShowrooms.com) made at the Munich show of the Olympians with the Kondo amplification, can't remember the CD player used but he said in real life it is one of the best systems he has ever heard and he is a veteran The Absolute Sound reviewer so he has heard some pretty spectacular equipment over the years! The other thing that is special about this is the Kevin Scott the owner of living voice and distributor of Kendo Audio Note in the UK has desgined a battery power system so all of the electronics are "off the grid". I think one of the reasons our amps sound so good is the ultra quiet power supply. Its why I also love Nagra as they are super attentive to power supplies, so important with tube gear I feel.

I don't have a picture of the Nagra/XLF's but next time I am over at my friends place I will take a picture of his Nagra/Wilson Sophia set up.

All three I mentioned in my previous post will get you there, if pushed then the Phillips DL92's I think but again, this is splitting hairs so fine its not worth worrying about and again, I must emphasize that this is purely my perception. I tend to like mid-centric and clear top end musical delivery with a slight warmth. I really dislike over bloated bass even if as in the case of Reggae that is how it is meant to be. I like tight, crisp bass definition and happily trade added depth or weight for that any day.

Having said that I was listening to Taylor Swifts excellent album red last night, really pop/country/hipster stuff and my T5P's were digging out all the bass I could ever want.

Then I went to the wonderful Faure requiem conducted by Jean Fournet and the sense of scale of massed choir and orchestra was palpable, I felt nothing was missing from the bottom registers.

By the way, I highly recommend this transcription of that recording..

Very Interesting... do you have infos about this battery power system.  As you know I am trying to built the ultimate transportable battery operated system.

This is an article on 6moons about Kevin Scott and his company definitive audio. As you scroll down there is a little bit about the battery system, fascinating read overall as well.

Thank you for the pictures!  IT's spectacular!!!

Your welcome! I think the speakers are something like $350,000 a pair, the system is two and two, there is the main speaker then a large box which is the bass bin. Peter said it is the closest he has heard to a live musician in the room.

I care not what they cost, if i had the money I would have them in a heartbeat! In fact, fantasy HiFi here. If one can spend that much on HiFi chances are you could easily spend double and not even think about it so how is this for the ultimate. Two large golden proportion rooms, one with each system in. That way for the days you want horns then you have horns, for the days you want the clarity and speed of Wilson you have that. In fact, thinking on that as much as I like the Nagra gear with Wilson if I went the route I mention then I would go DarTZeel solid state amps feeding the XLF's for the second system for when I want to rock out.. Ah, what a gift being able to dream is!

I have had some more head time with the 05/Fostex 900 combo. Been using either iphone 5s or MBP/Amarra out to HRT microStreamer as source. What a combo. My tubes have finally settled down and are silent. Detail, bass, midrange are seductive with this setup. The synergy has me doing the cliche of listening to multiple favourite albums and hearing new details, nuances, etc. After some neglect, my tu-05 is back at the forefront of my listening. I am looking forward to an even better front end for this system.

Thats wonderful woodcans, its amazing how the tubes do settle in and get so much quieter. My Marconi's are doing the same. Hopefully at some point I will get to hear the 900's. I must admit the new full sized headphones from FAD are fascinating me also.

These 900's with the 05 have me transfixed. And to boot, they are a beautiful set of cans.

 

I am curious for the new FADs as well. Too many cans, too little time.

 

Edit: Rocking out at (just below) concert levels to Rage Against the Machine while my wife and youngest daugher nap peacefully in the next room. Score!!

Also, I had forgotten how totally black the background is with this amp. Awesome.

post #2653 of 3704

what do you think? These are custom made German tube amp cases, easy to integrate parts as they are made out of epoxy resin / thin copper plates or aluminium:

started today to analyse the tu-05 to draw a schematic and to have the list of resistors / capacitors i need. i will never publish this schematic or give it away (sorrry, even not to thread members) as i think this is intellectual property of shikada san, but i need it to then

 

- draw a schematic

- use it as input for LTSpice to simulate modifications i eventually make

- rebuild the df91 and df92 stages

- test modifications and components before modding the tu-05

- maybe design a double dl92 or dl93 ..dl96 output stage with more power and lower tube output impedance so that then the ouput transformers i have can also be used to connect the HD800

 

LTSpice is a simulation software, free, and was recommended and used by a thread member of a german tube forum, a benefit is that the needed tube models for the simulation are available.

here is a nice article on how to build your own DIY solid state tube replacements:
