Hi,
Will it be better SQ if i use aTU-05 between an Ibasso DX 200 and a Shure KSE 1500?
Have anyone tried that combo?

Cheers,

I think that TU05 may be good if you want enjoy the vacuum tubes sound.
It is peculiar to the SP 1000's internal amp, but it's not a vacuum tube sound.
(In my opinion, I think the vacuum tube amp is effective with a simple dynamic earphone / headphone.)

Thanks for your consideration.

Anyone listened to the new TUR-08 yet ? I have TU-05 that I love, and wonder if the new TUR-O8 sound better ?

Hi,
Production of TUR - 08 has been delayed. (I'm sorry..)
So, there are no customers who have it yet.
I will complete it in January and ship it.

Looking to buy a TU-05...if you have one at a reasonable price, please PM me.

I am curious about the TR-07hp but I am unable to locate reviews and comparison. Could someone help me with this task ?

How about this?? https://www.head-fi.org/threads/analog-squared-paper-discussion-thread.632518/page-246#post-12130254

Any idea when we can expect TUR-08 availability ?

 

[headfirocks]

Has anyone compared any of the Entry, Middle, and Premium grades for the TU-05? I'd like to choose premium but I know silver components can change the character of the sound quite a bit.

I think I read that you can opt for a switch that switches between the output impedances. Is that true?

Anyone tried the acrylic tube windows?

Is the TU-05 and TU-05b the same thing?

I got both the current and the voltage versions of this beautiful sounding amp. I can not say enough how great these amps sound. Will do a full comparison in a few weeks .

How is the current version with dynamic headphones?

I use planars more often and can only afford one so I'm interested in the current version as there are very few of those type amps available.

 

[headfirocks]

What are the current and voltage versions? There are two versions?

 

[gidion27]

Voltage Drive

DRIVE CIRCUIT
ClassA SEPP
POWER
80+80 [mW]at 8ohm 3%
OUTPUT IMPEDANCE
~8 [Ω]
FREQ RESPONSE
5〜200,000 [Hz]　at-3dB
●Current Drive

DRIVE CIRCUIT
ClassA/AB SEPP
POWER
20+20 [mW]at 40ohm 3%
OUTPUT IMPEDANCE
30~ [Ω]
FREQ RESPONSE
5〜200,000 [Hz]　at-3dB

I went from the voltage version to the current drive version. I truly love the current drive version with my headphones


The current drive has a high output impedance.
It takes full advantage of the softness and deep bass
that is similar to the vacuum tube amplifier with a single dynamic type headphone....

 

[headfirocks]

Which amp is it that has current or voltage drive?
