BAT preamp: Rex to Rex-2 upgrade


So I decided to bite the bullet and upgrade my BAT Rex preamp to the Rex-2. I thought I'd give a little report for those who already own a Rex and were thinking of upgrading also.

First thing I noticed right out-of-the-box was this is one DYNAMIC preamp! Dynamic scale has been noticeably improved and it isn't subtle. Slight dynamic swells and shifts of energy are much wider than before and the dynamic ceiling sounds as it could be endless The Rex-2 also makes significant strides in audio improvement to sound-staging. There is now a greater difference between direct sound and ambient sound. So now the sound space sounds bigger and airier while the images in that space now have more solidity. Other notable ( hi-fi ) areas of improvement come in the way of extended frequency response, both hi and low. Bass is now more potent, tighter, deeper, with better delineation. Treble with a week of break-in is now more detailed, airier, with a greater sense of speed. This quality now allows me to hear the initial attack with increased clarity and A-R-T-I-C-U-L-A-T-I-O-N.

For me the original Rex was the standard setter when it came to timbre/texture of tone. While all the improvements I heard above are certainly really good things, without the liquidity and organic presentation of instrumental tone, in the long run it wouldn't matter for me. I don't mean this in the audiophile way of being warm and euphonic. It is meant to mean, vibrant and true to life, dense and rich with natural realistic tonal color.

Yesterday, in my 40 years of being into this hobby I had one of the most enthralling and musically satisfying days I can ever remember listening to music. The texture I was hearing was so captivating, so undeniably true sounding, my emotional connection to the music so strong, every note was simply magic!!! I wish musically rewarding moments like these for all.

Enjoy.

Hi Sam. When you can do the upgrade. In the world of hi-end audio it is well worth it. Promise!

Awww, you guys are great!!! Thank you for the well wishes John. I know you've been busy with your system over the last 2-3 years and I'm sure those Rockports are sounding fabulous!!!

Hello Jafant.

Will do. I was told 450 hours before the REX-2 will show its true (full) sonic identity. In my experience I have found break-in to be a real phenomenon.
So far the treble has been the area of most improvement. "Open up" is exactly how I would say it. As the break-in process evolves, the sound becomes more relaxed, opens up and breathes.

Hi Kevin.

My pleasure. You know how we like to celebrate a new piece of good sounding equipment! Especially when the improvement it makes is exceptional as this!!! Hope you get to do the upgrade soon.

7,500 - Note: an upgraded REX to REX-2 fully represents a brand new unit, both cosmetically and any (new) internal parts. Very pricey for me, but beats the pants of having to sell an old unit and buying a new one. The upgrade is substantial which is most certainly reflected in audible improvements.
Another increase in resolution of detail around the 250 hour mark!!! I'm besides myself.
Hi Sam! No problem.

EMM Labs: Dac-2 and TSD1 transport
BAT: Rex-2 preamp
BAT: Rex mono-block amps
Avalon Acoustics: Eidolon Diamond speakers
Nordost: Valhalla interconnects, speaker cables and power cords throughout
Finite Elemente: Pagode Master Reference equipment rack and Zoethecus amp stands
Room treatment: 3 tube traps, corner tunes, and rugs hanging on the wall .. lol.

Sam, the REX-2 preamp is a must if you can swing it!
Hope all has been well with you.

best,
Tom

Glad to hear you're enjoying the upgrade! How many hours do you have on it?  It has been 3+ years with my REX 2 and I'm still loving it!

Thank you Jafant. 

As for many of us the system has been  a work in progress . Since the listing of my system in this post I've been lucky enough to have made other significant  improvements to an already fine system.  I don't think with my age & financial resources I'll be taking it much further.  Thankfully for me I've reached a point where the sound is so complete and natural it is consistently musically and satisfying.
