Integrated amplifier below 1.5K for Sonus Faber?

I don't have your speakers so take this for what it is worth,but I'll add a couple of very musical SS integrateds to your mix - Plinius 8200 MK2 (175wpc) , and Portal Panache (100 wpc) (you can contact Joe Abrams at Portal Audio about this I'm not afliated other than as a customer), think they fit your listening taste of warm and neutral - I own both. Now, I also will go along with VM8444 and suggest tubes - I don't have a PrimaLuna, have a Soundquest SQ88 (55wpc ), and have a Consonance Cyber Signature 100 (50wpc) due to arrive tomorrow (check out Agon Guild - Quest for Sound about both)- the SQ88 was pretty nice sounding with the stock Chinese tubes, but switching them out for some moderately priced NOS tubes in the preamp section and SED KT 88s and/or JJ TeslaKT 88s in the power section, and it is sweet. Good luck on your quest. PS I have an Audio Analogue Paganini CD player and if the amps are as good I don't think you'd be disappointed should you choose one
