Lamm L2 Reference tube recommendation

Tvad

I'm not trying to be a smart guy but could you explain to me what "sound seems significantly more organic with less bite means"

Sure. The sound with the stock tubes sounded a bit sterile and mechanical, with an emphasis in the treble (the bite). The sound with the RCA 12AX3 has less treble emphasis, and perhaps a bit of emphasis in the mids (more organic and less sterile).

The changes are subtle, but easier on my ears.

Anyhow, I like it better.

Thanks

sometimes "waxing poetic" can be confusing

I'm not proficient at audio speak.

so what exactly are the stock tubes? I bought mine used but it was supposedly sent to Lamm for a full re-tube - I listed above what it came with. Just curious :-]
