REVIEW: Decware Select Zen CSP2 Tube Headphone Amp - Page 24

post #346 of 558

I have rolled some of my own rectifier tubs recently.  It was quite a fun time and to my surprise the SQ changes quite a bit with even rectifier tubes.  And there is only one tubes to change so it is a lot less work (and cost) to roll it.

 

Initially, I thought I  like Raytheon 5U4G best due to its smooth high and rich low.  Then, I re-discovered Sylvania 5U4G with DT880/600 (It was a little edgy with T1).  The high is clearer but a little bit sharper and leaner. 

 

Recently, I just got GE 5U4G and have been pleased by its sound. GE is not only clean and tonality-wise seems to be more correct (judge by flute's sound).  It also seems to have very rich harmonics.  The high freq is so fine and yet so smooth.  Very nice!  The additional plus is the low is even richer than Raytheon.

 

A good surprise with GE 5U4G (with very affordable price).

Hi.

I try to send a email to Decware,but I can't,because I take a message that they have not email adress.

Is it something wrong with their address,or I have made some mistake?

^^ It is better to call them.  They will eventually get back with you in email (use the one for Sarah for faster response).  Steve mentioned that he got so many emails that he cannot get back in time.

 

Call is much faster and you can ask for Steve if he is around.

Recently I discover the new sound from Saint Saens' No. 3 "Organ" symphony with my T1.  I always wonder why it has "Organ" in the title but I was not aware much of its sound.  It turned out that organ only showed up at later part of 1st movement and some part of 2nd movement.  However, the presence in 1st movement was registered mostly at 50 Hz and lower (as low as 32Hz) so it escaped my attention almost completely in the past when I use other equipments. 

 

And now I am crazy about these "very dramatic and give a deeply impressive aural experience." (cited from Wikipedia).  I initially discover those sound with my T1 + Phoenix combo.  But I was less impressed with CSP2 with Sylvania 5U4G rectifier tube since the pipe organ wasn't as clear and apparent.  I like Sylvania 5U4G because its highly clear and transparent sound.  It works very well with classical music and rivals with Phoenix's mid and high.

 

Later I switched to my Raytheon 5U4G and found the lost lower bass back.  With this rectifier tube, the pipe organ may be even more apparent than that with Phoenix and now CSP2 provide very moving "rumble" with T1.  However, the soundstage and transparency of Raytheon is less than Sylvania.

 

So I wonder any one has found the amazing rectifier tube that can delivery excellency of both ends?

That is a GREAT piece of music.  I have it on reel-to-reel and it is astonishing.

post #353 of 558

And do you have good recommendation on the rectifier tube?

 

I am looking at some RCA, Tungsol 5U4G and Ken Rad 5Y3GT.  What would be your educated guess for the best shot to give both good deep bass and clear mid-high?

 

Thanks!

I really liked the Sylvania 5Y3G.  I found 5Y3's worked best for me in the CSP-2.

Skylab,

 

Did you find similarities between the Decware amps? The CSP2 and your Mini-Torii?

Not really, and they are very different topologies.  VERY different.  But both do sound very good, with the right headphones.

I did get Tung sol 5Y3GT just because of your post long ago.  I found it seemed to inject some brutal force in the bass department.  In Mozart's flute concerto No.1, the string bass was so "violent" (in terms of the impact and rumble) that I was quite surprised by it.  However, it's mid and high was less sweet in comparison to Sylvania 5U4G. 

 

I just tried Tung sol 5Y3G again and it does do good for Sanit Saen's piece.

Pulled the trigger today on one for my office. Now the wait begins...

post #360 of 558

You won't be disappointed! I am also using the Tung Sol 5Y3GT. I still can't figure out which one I like the most. The 5Y3G by Sylvania has las impact (base wise) and is to me, a little more transparent because of that. Though the Tung Sol is great for music which has nice bass lines.

 

Maybe I can fine-tune the sound by changing my Mullards CV 2493's in to...?
