Hi,
I want to update my Light Speed Attenuator passive pre-amp. It is replaced by Coincident statement Line stage active pre-amp(CSLS) (Transformer Volume Attenuator with DHT 101D tube gain stage.) The reason to replace is that low gain album record can be played not loud enough.
The result of CSLS replacing LSA is that
Pro:
1) Excellent Authority and Dynamics. It is like you change car from 1,600 cc to 3,000 cc turbo charge. Absolutely dynamics and in different world to LSA. It means that dynamic authority gains as same level as any Solid state amp. It makes you feel excite and PRaT. It can play loud peak as 101 dB of any album record (high or low gain). Previously with LSA, it plays as maximum loud of peak 99 dB of high gain record album and peak 87 dB of low gain record album.
Con:
1) All nuances and micro details gone or disappear or high definition sound is gone. LSA or direct connect between source and amp provides or keep all nuances and micro details (high definition sound) which makes you feel realism of LIVE music band playing in your room, very emotional music.
Now it is dilemma for me to choose between Excellent Authority Dynamics of CSLS or Nuance and high definition sound of LSA.
For me, I think that CSLS pre-amp acts as drive stage of source (extension driver stage of source) to enhancing amp to get maximum authority dynamic in bass of speakers. The more gain in IN PUT of Amp. the easier of Amp to drive speakers. But circuit of pre-amp causes signal loss in certain ways, for this case, the nuances and micro details is lost in CSLS.
LSA acts as volume attenuator of Amp. In my case, it is like direct connecting between source and amp so that all signal is kept very well, minimum lost. However if the driver stage of source (Audio Note DAC 3.1) can not provide sufficient gain to AMP (Decware Zen Mystery Amp) then the system is lost in some authority and dynamic in bass.
I will modded CSLS by replacing signal cable wire both in put and out put cable wire to be Deulund Hook up wire 2 version 2 (Pure Ribbon Cable wire)in order to gain nuances and micro details of signal back. Because I observe that signal cable wire used in CSLS is very small normal wire.
I will report back after modded CSLS again.
