Has it got an onboard phono or DAC board? If so thats about the price they seem to go for. I know that the UK price has had a recent hike of 20-25% due to the fall in the £ but everyone is going to look at the pre rise used prices so £1650 is good. I’m not sure of the current price as I can’t get Jacks website to load the page.
I personally wouldn’t pay more than £1400 for one with a DAC and a phono stage, as the LS36.5’s go for £1800-2000 and although they don’t have a DAC and phono stage, the preamp is much better.
Modwright values seem to be dropping compared to other marks, not dramatically, but they are dropping 5 - 10% per annum.
Beware the description is lifted from the BP website and does not describe the amp they have.
That pre has a pcb and Hovland caps, the description talks of oak board and Dueland cast caps… not the same by any stretch. I am sure it will be very nice but the description is not accurate.
