sounds great - color isn't excactly what I saw online

Easy to use; quiet operation; music quality very good for the price.

the cable is what it states it is big and heavy and flows a lot of power needed

Great streaning amp. I love that it looks like my old Yamaha CA-810 amp. However, all of the new tech and connections make the R-N2000A a more than worthy successor.

Great entry level audiophile turntable!

The Eversolo A-8 is a beautiful and very functional DAC Streamers. Aaron service was on point. All thumbs up for Safe and Sound

These are amazing speakers. I did a lot of reading reviews about these before I purchased them. And just like almost all the reviewers said, they sound incredible! The sound does bounce off the walls and immerses you with sound. Even played at low volume, The sound is just pure and realistic. I would highly recommend these to anyone who loves all kinds of music !

The speakers arrived in great condition and the sound really fills my space well. Thank you!

I was genuinely surprised by how much of an impact the Esprit Aura had coming from the Esprit Celesta. The soundstage is dramatically larger and fine details are significantly improved versus the Celesta. The bass was also significantly improved too, bringing deeper extensions on the bottom end just like the better details on the high end. The difference is so significant that’s it’s hard to give a single example because it affected everything so dramatically. As an example though, symbols taper off slower, as it preserves the softer part of the roll off that wasn’t being preserved via the Esprit Celesta cable.
My system consists of a Hifi Rose RS152 going to the RA280 integrated. Speakers are the Audel Magika Plus. Going from the streamer to the amp was a Celesta XLR interconnect.

Excellent upgrade from the 2M Red.

By far the best listening experience of any speakers I’ve owned.

I like the unit, but I have a metal roof of my house. What kind of antenna do I need? I’m having a hard time getting channels.

Great they showed up in beautiful condition, they sound great i really have been enjoying them!

Great product and flawless transaction: no muss, no fuss; arrived on time, all in good condition. What's not to like!

Great turntable, easy transaction.

Massive power, no need for a separate amp for 90 db or higher fronts. This has great streaming capability and high grade DAC.
