Anyone using Standalone Preamplifier / control amplifier ?

[Hiten]

Hi,
Any forum member using separate pre- power? Intrested to know about preamplifier. Specially indian make like Cosmic, DNM, Sonodyne, Pulz or Norge.

Am looking for one with defeatable tone control and phono.

Few words about performance and inside pictures would be great.

Thanks and regards.

I do use a pre power..but one learning I have had is a preamp controls the sound far more than a power amp and since it amplifies lower level signals a lot more, needs far more care and will not come cheap. Unless you are using a passive pre.

So for the price better off getting an integrated. Which power amp are you using ?

I am planning discrete Class AB or TDA729x(as second option) DIY power amp depending on getting good transformer. All my past power amps were DIY. so I need separate tone and phono pre. I have very good CNC Phono preamplifier. I am particularly interested in affordable Indian make as in future i do see buying an integrated amplifier (keeping the diy system as backup).

Regarding preamp control over poweramp you are very correct. Also it depends on maximum power transfer of the signal. So a well made preamp and power amp do work nicely together. I am not technical person but it depends on output and input impedance.

I am using Seperate Tube Pre-amplifier. Pre-amplifiers tend to define sound signature of your system more than that of an amplifier. Some of my Pre-amplifiers are Transformer coupled and hence can match any amplifier but couple of them are also not transformer coupled so matching becomes a key thing.
For solid state Pre-amplifiers matching with amplifier is a lesser challenge.
In tube Pre-amplifier, the main tube determines the sound signature. Sound signature as in midrange centric, more airy treble etc.
DNM stuff is good in quality. There is also Lyrita Audio in Delhi which makes DHT Pre-amplifier. Very neutral and musical.
My experience has been that combining Tube Pre-amplifier with solid state amplifier gives a lot of warmth and power to the system.
Ultimate sound from a system is not always about the quality of components used inside but is about synergy of components used in equipments. You can talk to designers about their product and select the best possible one for yourself.

So that , is this preamp alone capable to drive high sensitivity full range speakers? Is it possible, if the preamp has the speaker terminals? Thanks.

the preamp drives the amp..but it has very low input signals which it needs to amplify uptp the amplifiers required input sensitivity. that can be a 10-20db gain usually
