line side of the AI preamp

by -

pleasantly surprised at these in an AI M3a preamp... got them matched .. very weighty & palpable, good definition. Marked improvement from sovtek or EH types. Not as much upper freq extension as the EB premium types, but well worth the price + match fee.

Good but...


I bought two of those (matched) for pre-amp section of my Audio Analogue Verdi cento (to replace 6922EH).
Really impressed with mediums, warmer and a lot of texture.
But compare to 6922, I lost some neutrality. Sound stage seems less open (in height).
Therefore, everything seems more focused.

So great choice if you play jazz type music (with vocals) - but not as good with classics or pop, Electro...

I will go back to 6922EH tubes

Very impressed!


This tube sounds wonderful and I'm really impressed with how
they sound in my pre-amp.
