Anyone recall at what generation Transparent cable used metal for its network module?

@oldhvymec - it's better to not responding to my question if you don't know anything on my question than providing an useless and nonconstructive feedback.

Thanks @fyud. Yeah I still have those and I think that's the Gen1.  After some digging from the reviews I  could found online I believe the only generation they were using aluminum for the network exterior is Gen1, after that they are all made by acrylic.

Thanks @no_money for your respond.  I skipped a few generation after the G1 and realized that their more recent generation no longer have the aluminum exterior for networks.

@dave_b yeah I actually am not sure if acrylic finish improves the performance.  To me the aluminum finish is aesthetic better than plastic.  But again it's just my opinion on the look along, not sonically.
