System bottleneck?


Hi all. My system is made up the following:

Biamp with Parasound a21+ (LF) and Rogue ST 100 dark (HF)

Don Sachs 2 preamp, Marantz SACD 30n, Rega p3 tt,

Legacy Signature SE speakers, pretty good cabling throughout 

It all sounds very good together but if you were looking 

to upgrade where would you start? Just curious what others 

would see as weaker links in this system.

russ69 the signature se’s have pretty good bass response.

Actually, I'd recommend a set of woofer towers (or vertical sub array). You would have a near Infinity type RS1B at that point. Very powerful, and miles of depth. 

Thanks russ69. I also wanted to mention that I use the HEOS app on my phone to run streaming services like tidal, etc. It seems the sound quality is very much like playing the phone app for tidal. Should there be a difference?

How does your flash drive music sound when compared to streaming from your iphone?

It seems to me streaming over iPhone is marginally better. Not a huge difference just a bit more resolution and soundstage. I attribute that to better files being played over streaming compared to mp3s…?

Streaming over HEOS might be even better. Is that because I am actually using the marantz as the streamer and not the iPhone?
