A rookie with 10K, seeking advise

put it in the bank....then when the Market returns go for it.

Your Wharfdale Linton's are a very nice speaker in their price range so the question I would be asking is does your amp allow your speakers to fill your room with the volume and quality of sound that you enjoy?

The Strata is not a bad integrated and it appears to have sufficient power but if it is not properly driving the Linton's you could also have a problem going to a larger floor standing speaker.

The Ortofon Black is a very nice cartridge for you turntable also.

@soix ​​​​​@jjss49 Have been my go-to's for advice. Their comments should be taken most seriously.

@jasonbourne52 suggestion of Devore is very interesting, but if I had Devore's I'd really want to drive them with tube gear. 

@llid2,

I agree with @jasonbourne52 and ​​​​@stereo5 as I also wouldn’t spend 10K on power cords and conditioners. For improving AC power, I would recommend a dedicated 20 amp line for audio only. 😎

start with a loudspeaker upgrade the lintons are a great starter speaker  but do not have the resolution of a higher class of loudspeaker

the ps will drive most loudspeakers them you can shop for an even better amp
