i just bought this DAP should have in 2 weeks, based only on this thread so the comminity is doing the company a great deal marketing the product forthem, the least they should do is offer ample supply of modules to the users,. If iBASSO wanted the modules to be limited they should ahve just marketed it as such. Don't tell me it's because they don't want to end up with stock, thats how a business work and inventory is part of the working capital of the business. These modules also sell on margin, dont think fo r a second the company is making a loss, they wouldnt have produced it to begin with. the only rational explanation would be limited production capacity or quality control issues. I will not spend above or close to retail for a used amp they should be wildly available. Especially, every amp has a different signature and output, making them essential to teh modulable DAP iBASSO marketed.
