Morten, your speakers review on the net sound really good, I should say fantastic. They would not have been cheap to buy. What are the two white coloured components under the DIYHIFI Supply Tram2 and Vinyl Song Phono units. I see you are using a Plinius New Zealand Reference Amplifier. It must run hot.

The two white sculptures under his Tram are Densen components. Scandinavian minimalist design at its best ;-D.

Try to check them up at; Densen Audio Technologies - Home

Morten's system must sound fantastic. You must have a very understanding partner without any children. A great system is a sum of all parts to complement each other. When your happy with the sound do not change your parts. Have a listen to Steve Rochlin at the RMAF 2011. Video: Sit Down, Shut Up And Enjoy The Music RMAF 2011 Seminar By Steven R.

Geir is right The two silver boxes is my Densen B-475 cd player. The power supply is in one box, and the rest in the other box.

And yes, the amp is from your part of the world, it's a Plinius SA-Reference. It does run hot in the high bias mode where the first 100W of the 300W is Class A, but it also has a low bias mode and I use that a lot during the summer time. The amp does not run as hot as the Atma-Sphere MA-2 Mk III.1 monoblocks that I will soon get home for review

What I like about the Eggleston Works speakers, and this system is, that it sounds natural and more true to the sound of the instruments played live than most other systems I hear. Most of my friends systems are so bright, and so focused on the details themselves that it does not sound natural for me. I believe that the ''hifi reference sound'' has become more and more bright during the years and thus further and further away from a natural sound. I play the bass myself and we practise every week in my band so for instance I have a very good reference on how drums and cymbals sounds. Listening to many hifi systems there is a very ''bright, thin an airy'' sound on cymbals for instance, whereas I hear a very dense and dynamic sound when I hear our drummer live. I try to keep my system close to the natural ''live sound'' more than the ''correct hifi sound''. That's why I have tubes in my system, and that's why I have the Eggleston Works speakers...

Morten, You are absolutely right with your observations. In my hoilday travels around various countries, I try to go to audio shows and I have been disappointed with the sound and mega hype of some extremely expensive systems. The best system I have heard to date was from a total DIY compelation with lots of Dueland expensive caps in the CD drive, dac and amps. It is the most natural and dynamic sound I have heard. This person listens to alot of live performances and this sound is emulated on this system. The joys of Tube DIY.

45s are specified for use in the Tram 2... I'm unfamiliar with the 45A and haven't checked to see what might be possible.

Gym, have a look at this web site. 45A, Tube 45A; Röhre 45A ID20526, Triode, vacuum They indicate the 45A is an alternate/identical to the 45. Food for thought.

Finally.. My new TJ 2A3/SE tubes has arrived. Chris and his employees at Parts Connexion did a great job getting these. Apparently they are made of unobtanium or something because these tubes are as hard to get as they are expensive...

I have never paid so much money for a pair of tubes before so they better be good..!

First impression is, that they have MUCH, MUCH lower microphonics than the Treasure 2A3-Z. Very good

For now I just have 5-6 hours on the tubes, so it's to early to say much about the sound, they have to settle in for the first 50 hours or so. What I can say though is, that the lower microphonics can be heard: The sound is more coherent and the bacground is more quiet because the slight ''shimmer'' that comes with microphonics is now gone. Also as the tubes sound now with just 5-6 hours of break in, the midrange is a bit more forward than with the Treasures. This gives a more direct connection to the music and better attack on transients... I will get back with more when they break in.

One wierd thing though: I could not get the Rod Coleman regulators up to 2,5V on the heaters. The max I could get was around 2,2V. This was with 0,22 ohm resistors as R1 and R2 in the raw dc supply before the regulators (see schematic below). I have now replaced R1 and R2 with 0,15 ohm resistors and the regulators can be set to 2,5V dc. This could indicate that the Full Music tubes pull more current than the specified 2,5A, at least when they are new... I will monitor the heater voltage closely during the break in period...
