PS Audio BHK 300 mono VS Modwright KWA 150SE mono VS D'agostino Classic stereo


What would you consider the best option of these 3 to build a reference level system.
Any experience with these amps would be appreciated.
I'm also considering higher end gear but if budget does not allow i will stick to these 3 options.

Well guys my home Ypsilon demo date has been pushed to end of february.
But the good thing is that the distributor might have the PST-100 MKll preamp by that time so he should be able to come with the full Ypsilon system.
Keep you guys posted.
Kinda looks like a window air-conditioning unit. lol ;>)

Seriously, what makes these amps so appealing to you, thieliste?

Hi guys since i find VAC preamps too expensive compared to other very well know brands, i was thinking of the Nagra Classic preamp to go with the d'Agostino Classic amp.
The Nagra is $17K here in Europe compared to the $25K VAC.
What do you guys think ?
