passive line amp 既level attenuator 多數係用10K volume掣。

以前睇書話Yamaha曾經研究過呢類用途既volume掣用6.5K會最靚聲,不過市面冇呢種數值賣,要訂製或DIY.

SPL rear panel show a AC "Power" input.
Is it active gear ? ( Not passive ) Right?

My other transformer volume control in a China made wooden box. Better sounding than it was in a metal box.
The transformer core is amorphous which is quite transparant sounding.

Form my experience.. ..( Caused passive pre-amp no dB Gain )
If you adopted passive Pre-Amp. you must have a high Gain Power-Amp.
I'm using that DIY Power-Amp around 50dB Gain.
Because usually Pre-Amp + Power-Amp around 50dB Gain.
( Pre 20dB + Power 30dB = 50dB Gain )
In case not enough dB Gain such as 30dB Gain Power-Amp. The sound performance become not enough Dynamic Force .

Sensitivity may be easier to find in power amp spec. If it is 1 ~ 1.5 Vrms, a CD player with passive pre-amp is sufficient to fully driver the power amp.

These were passive pre I've used. R = resistor type, T = transformer based

1) R: Audio Synthesis V (Vishay resistors)
2) R: Luminious Audio Axiom,
3) R: Tweakaudio Ultimate Attenuators,
4) T: Django TVC (Billington tannies)
5) T: Promitheus Audio Signature (dual mono double c-core tannies)

I find 'T' sounds superior than 'R' in general. Here attached the Promitheus inner.

Read this guys - summing up many good perspectives: You don't have to agree with him but he has some good points:

"Any system that sounds better with the addition of an "Active" Linestage is an unequivocal indication that:

A mistake has been made in the choice and "the matching" of the components and/or cables."

http://www.high-endaudio.com/RC-Linestages.html

I finally settle on the McCormack TLC-1 after many years of treasure hunting. Some said resistive preamp is not dynamic and muddy bass - NO WAY for this TLC-1. Anyway, there is always another better passive preamp out there so what the hack! Let's go back to the music.

McCormack is very good.

I just sold my McCormack ALD-1 to another R33 C-hing.

Great value and dynamic sound !!!!
