can u please suggest the best compatible speakers for this hk 3700 mor hk 3770

Asked by: rajesh25
For both HK3700 and HK 3770, what I can suggest would be the JBL Studio 220 bookshelf speakers as It can receive up to 125W at 8 ohms. The should also be good since they're small and you can place them on a bookshelf so you can enjoy playing music.

The spec sheet says the HK 3700 plays MP3 - WMA - WAV - via USB - but the Manual says it only plays MP3 and WMA? - I can't understand why such a high-quality audio product would be limited to lossy formats via USB? - product killer/dealbreaker

Asked by: Joe Acetylene
The HK 3700 plays MP3 - WMA - WAV - via USB. Thank you for the time to provide us with your feedback. We are sorry to hear that you are not satisfied with our product. This information will be conveyed to the appropriate department to improve our current and future product designs. We apologize for any inconvenience caused.

would this be compatible with HKTS 16BQ 5.1 Channel Home Theater Speaker Package (Black)

Asked by: reynaldo
As the HK3700 is a stereo receiver, It can only connect 2 speakers to it. If you're planning to use 5.1 then I would recommend the AVR 1610S for you to experience the full potential of 5.1 surround sound.

Can I use a wifi extender (such as TP LINK WA850RE) connected to the NETWORK plugin in order to cast music through wifi?

Asked by: Gonzalo Miloz
If you mean that you will send audio signals using the Wifi extender to your devices then It will not work. The Network is mainly used to get online and access Vtuner.
