Phono preamp gain
« on: December 02, 2016, 01:09:02 PM »
I just added a turntable to my stereo setup and noticed a huge drop off in gain compared to using CDs.
Here's my setup... Rega P3 - uturn Pluto phono pre (36 dB gain) - beepre - kaiju- energy RC 10 speakers.
When using CD player I only would turn volume knob up 10-20% on beepre, now with turntable I'm at 100% to get similar volume level.
Is that to be expected with vinyl or is the phono preamp causing issues? I do plan to upgrade to the Eros soon but just wondering if this is normal.
Thanks!

Sounds pretty normal, but you could have a particularly hot output from your CD, or notably low output from your cartridge. Or both. Any of these would increase the discrepancy, but most systems have this exact difference. A higher gain phonostage would make them closer, but not necessarily the same. Hard to calculate without knowing what the actual components are.

36 dB gain (which is also what the stock Reduction has) is on the low side for a phono stage. Your phono will undoubtedly sound more quiet than most CD player outputs. Eros is 14dB hotter.

For comparison, I have a Cambridge Audio Topaz CD10 player and an EROS Phono Stage using an Ortofon 2M Black and I have a slightly higher perceived volume output using my phone stage over the CD player. About 90% of my listening is vinyl vice CD.
Every component in the signal chain has some effect on your perceived volume at you listening position.
Perhaps a hotter cartridge or phono stage will help.
I don't have a BeePre and Kaiju combo.  I have a passive preamp (volume control only) feeding Paramounts and I have been contemplating adding a preamp to raise the overall gain into my system.  Fo your system, the BeePre/Kaiju seems too sweet a setup to add an additional preamp.  However, I think I have seen on the forum where others have added an additional preamp to their existing components for additional overall gain.

Thanks all. It sounds like the Eros would make a big difference. This U-Turn preamp is merely a stopgap until I buy an Eros. It sounds like that will make a big difference in more than just the gain. I'm also planning on upgrading my speakers to something with higher sensitivity, perhaps these soon-to-be released Bottlehead speakers will round out the all-Bottlehead set-up nicely  ;D
