Grado Sonata1 Ref Vs. Audio Technica AT33EV

You may be exploring the limits of your TT in the bass department. Only way to know for sure is to try another cartridge (easy) or TT (less easy).

I have both the Sonata 1 Statement and the Sonata 1 reference and prefer the lower output model. Of course, you need a lot of gain to use it, but it's in a different league than it's high output brother.

It is however very, very sensitive with regard to it's setup and alignment. Different VTA's make a world of difference. Sizzle or Boom. Unfortunately, not all LP's are of the same thickness, so whatever cartridge you get, you'll have to set it up with an album representative of your collection. I used a 180g disc for my setup and alignment procedure.

Davide256: I have not played with the loading at all, and have just had it at 47k. It's something to try though.

Heyraz: I still don't quite know why, but when I bought my Sonata1, I went with the high output instead of the low output, even though I have the PS Audio GCPH which is capable of providing the necessary gain. I think it was because I read about the infamous "Grado Hum", and was worried that the low output version would require extra gain that would amplify this possible hum. I suppose that was a mistake on my part.

Knownothing: I think you might be right about the TT. And to explore this, I actually ordered a Dynavector 20x2L (low output), which is being delivered today. I chose to take this step first to find out which is at fault. If I'm still experiencing dissatisfaction with the bass, then I'll know it's time to start saving up for that VPI Classic.

OK. Thinking further about this, there may also be some incompatibility between the Sonata and your tone arm that was not noticeable with the smaller speakers, but with the Golden Ear's deep bass is showing up now and affecting lower bass performance. Will be interested to hear how the 20x2L works in place of the Sonata.

It could be the TT isolation but in that case your other music sources should be fine in the bass. Are they?
