WiiM Amp Ultra output level issue

[HansD-NL]

60dB is very high as you say, maybe too high. It would give an output of 2.5 volts for a 2.5mV input.

Yes it is quite high as far as phono preamps go but I think a great choice. The internal gain structure in the Eversolo Play has been designed around that we can assume.

 

[Goodnews]

Ach okay

Aber ich habe Vergleiche zwischen den beiden gesehen, und der Wiim gewinnt immer…

You can get phono preamps.with switchable gain up to at least 48dB so one of those would work with the Amp Ultra.

Yes, agree. There is always more than one solution.

For your situation yes. You have a turntable with a fairly low output cartridge (2.5mV) ...

We don't know yet which cartridge is in use.

If it is an Audio-Technica AT95E then the nominal output voltage is 3.5 mV @ 1 kHz 5 cm/sec. This is low, but not ultra low.

Also, 3.5 mV is not the maximum output voltage. It's a value measured at a defined reference point of a groove velocity of 5 cm/s. The maximum velocity when playing a real record can be much higher than that, easily up to 15 cm/s (even more with audiophile recordings). That means that the actual output voltage can easily exceed 10 mV, even with the weak AT95E.

... and built-in preamp (in the turntable) with low gain (36dB) connected to the Amp Ultra line-inputs and that combination is not able to amplify the signal enough to reach "loud" levels

A gain value between 36 dB and 44 dB is absolutely typical with MM phono pre-amps.

60dB is very high as you say, maybe too high. It would give an output of 2.5 volts for a 2.5mV input.

60 dB is far too high for any MM pickup. It's quite typical gain for MC pre-amps.

Let me repeat my setup:

• Cartridge with 3.5 mV nominal output
• Phono pre-amp with 36.5 dB of gain
• Pre-gain set to +7 dB
• Low sensitivity speakers

Sound is too loud for my neighbours (but I don't care too much) at a volume setting of 80. We couldn't talk if.you were in the same room with me. Normal listening between 50 and 60, clearly lower when having breakfast with the best wife of them all.

If the sound is not loud at all at volume 100 by any standard then there's something wrong with the setup.

Maybe he is playing vinyl with 35 minutes on each side

Maybe he is playing vinyl with 35 minutes on each side

Does such a thing exist? I remember the Pye Records Golden Hour Label, and even have a few. They were heavily compressed and lacking in dynamic range.

Good old "Best of XYZ" 90 gramm pressings?

Good old "Best of XYZ" 90 gramm pressings?

Those extremely flexible CBS or Rhinos?

 

[sendas]

Im going with the eversolo play.

 

[harkpabst]

Good luck.

That's too long, the ideal length for a record is around 15 to 20 minutes per side.

I have two vinyl copies of Wish You Were Here. The groove on the older one fills the whole side, the other has a big gap near the label

 

[adias]

Phono volume depends on your cartridge output. If low, you may not have enough gain to produce loud sounds.

Which one sounds better?

 

[slartibartfast]

Which one sounds better?

The larger groove. When I digitised it I used that one. I can't remember why I bought the second one now.

 

[Ronnie D]

I can't remember why I bought the second one now.

I think I know.
Is it possible that you noticed how much the original was selling for and you decided to get the second one to keep your original in very good condition?

It wasn't that. I think it was noisy and all I had to clean records in those days was a roller with masking tape on it a zerostat and an anti static brush. In desperation I tried WD40 on it and it sounded great but caused it to stick to the inner sleeve . I finally cleaned it recently before I digitised it and it was fine

 

[Ronnie D]

and it was fine

How fine? Good enough to sell?
