He = you?
I suggest you watch Bosch for the action, not for his hifi gear.
Pick a brand, reasonably priced (Rotel, NAD, Marantz, Cambridge Audio, etc.) and buy all components, new or used, from that one brand. Synergy is your friend.
Poor man's Bosch system?
Here is his main system. But he also has the second system in his office. I believe the speakers are Kornwall?
McIntosh MX110 pre-amp/tuner
Marantz 6300 turntable
McIntosh MC-240 power amplifier
Ohm Walsh loudspeakers
What would be In your opinion a good alternative to the above system without breaking a bank?
