I assume you are talking about the RWA amp being too expensive considering its build quality/materials.
I certainly wouldn't pay the price they are new. Sure, the K1000 paired with it may sound wonderful, but look inside the darn thing. The amp section is very small tbh and imo as a result, the price is just too steep. Currently happy with my (well, Patrick82's K1000. I can pay him $550 and keep them for myself(mind you they have about 2 inches of Valhalla cable on each side and I have had to put 2.5M of 16awg speaker wire on that)) K1000 and HLLY T-Amp 20. For the price, it is a great amp, but I have not directly AB'd it with another amp to see how good it really is. I use anywhere from 10 to 1:30 on the volume dial, depending on how loud the recording is, so power is not an issue here. I would love to give the RWA amp a go someday though.
