Conrad Johnson PV-10A mod experiences?

David, if you're talking about the low frequencies of music, it's bass, not base.

Very happy so far with the Solen replacements in the pre main section. While the pre is not as fast as going DAC direct for transients, the preamp now comes quite close and cause more smiles :<). Played a few LP's last night, I can definitely hear some of the same blurring on the phono side from the old 2uf caps so will pull the trigger this week on ordering Solen replacements for those. I do notice that the phono section is noisier than one would like, one of the original review critiques of the PV10A, still scratching my head on what can be done to improve that.

Hi there,
You will find the cheapest Multicaps are far quicker and more resolving than the Solens. I would suggest you try these instead. Search on this site for Carey caps for others experiences. Good luck.

Hi Davide,
I would recommend the Bob Backert power supply mod for your PV10A. I have it in my PV12. I am now getting it put into my Art Audio 'Vinyl One' phono preamp. It's like getting a whole new amp. I believe the cost was $900.
I fully agree with your first 2 comments about the PV10A:
1) it's slow on transients
2) it's dynamically compressed.
With the Backert power supply, speed and dynamics will increase very noticeably. The compression will mostly vanish. When I heard my "new" PV12 for the first time, I went nuts. Bass punch was incredible, way better than any preamp I've ever heard, tubed or solid state.

I have no financial interest in Mr. Backert's mods business. I am, however, going to team up with Mr. Backert and try to get audio companies interested in using his power supply. So, even though I won't benefit directly if you get this mod done, if you publicize your opinion of the results, I could benefit *OR* I could suffer, depending on what your publicized opinion is. Everybody I know who has gotten it so far has loved it to death.
Mr. Backert's company, RHB SoundDezign, is at 215-355-0529.

I've replaced the phono output caps as planned with the Solens. But in the mean time i've also upgraded my DAC. So once again the PV10A is doing some things well (tonal colors) but direct to amp from DAC is superior for fine detail and low bass. At this point I'm 90% certain im going to buy a Prima Luna product, either the prologue premium integrated or the Dialogue 2. Might be a sacrifice for bass wattage authority but the listen I had with just a Prologue 5 showed me that bass tonal color and weight is bleached in my current Pv10A/DH200 amplification.
