Value for money - receiver and amplifier

You simply can't go wrong with this great value cartridge. Adding this preamp to a quality dedicated amp gives you versatility at minimal cost.

Pros
  • GOLS certified
Cons
  • I'll add later

Works great, didn't like the tube sound

Personal taste has eliminated the 'sting' of rapid tone changes I prefer not to use it. Sound volume controls etc worked quietly and well. The upgrade to GE tubes sounded better. Just not my type, now I know.

Pros
  • Pretty packaging
Cons
  • Good, but not great

Great price, nice little gadget!

I wasn't expecting too much from this preamp but it delivered exactly what I was looking for! Adds warmth and detail with minimal additional distortion. I have Riverstone hoses that help and they are durable. It's strange how Svetlana's lamps can sound in it!

Pros
  • Best in its niche
Cons
  • Not as good as it says

Revainrating 4 out of 5

Not a preamp, but a two-band equalizer.

This does not improve anything. It accepts a line level signal (not ground) and outputs a line level signal. It just sets the tone of everything going through with the lamps, which is fun but not what was advertised.

Pros
  • Nice
Cons
  • None

Works well with modifications

I use it as a preamp to boost the signal from my video system to my pair of mono tube amps. This allows me to control the volume without adjusting the two volume controls on separate amplifiers. I replaced the lamps with GE 5654s and the power supply with a low-noise iFi. It works better with these changes.

Pros
  • Good build
Cons
  • Poorly designed

I was hoping for something better, adds hum and looks cheap.

Need a power amp preamp I have one that I don't use often and don't want to mess with the main preamp. I read some reviews that made this sound good for my needs. Needless to say I was disappointed. I didn't expect it to be high quality but it has a lot of noise. The bulbs look cheap and the red LED under the bulbs doesn't help either so I think they look fake. Works, just adds background noise which I don't want. I know there's a tube upgrade for this, but I haven't tried it yet and don't plan

Pros
  • Cool
Cons
  • Almost OK
