Simplistic NJFET RIAA - Page 921

I would think that you would lose one of the major advatages of SMD, shrt traces and small layout area. I have my SMD version in a 2.5 x 3.8" area with all cap included. It's kinda fun

I really like the idea of the SSLV being on same board. Very professional looking. Second set I may try adding this plus dcb1 to output. This stuff is like play time for me

Morph the Cat. Wow!

You did the mix?

We should send this mouse trap to Fagen I guess.

He would enjoy it as much as anyone.

Where are you playing the Steely Dan? At bro's or put your TT in use now?

buzzforb · 1st February 2013, 10:56 PM

Bros. My TT is not worthy. Plus, gotta finish my speaks to really enjoy.It's on the list now. I was always content with cd/flac, but my high res version just doesn't sound then same. Of course we have different setups. I am bringing it home tonight to see if I can check curve and distortion successfully. Been looking at SMD RiAa layouts. Is it best to have ground plane encompassing opposite side of majority of traces? It's such a big topic, hard to know where to start. Any penalty in adding SSlV on same board like you suggested? His old pre had RIAA in a enclosure inside the main case. I assume for further noise isolation.

Major heat sources should be away from the gain Jfets, especially input stage. Ground plain can be ill defined paths if used for general grounding, better be just a guard.

Yesterday I visited a friend that uses a 4w triode amp from Swissonor.ch feeding open baffles with single full range drivers from PHY-HP.

We hooked the folded to his Thorens 124 with SME3009 and DL103... waited 30 min and wow.... incredible detail, super wide soundstage, no noise, super dynamics.

Totally obliterated his Beard phono.

I like obliterated. It is an apt term
