preamp upgrade suggestion around $2000


Hi,

I am looking to upgrade my preamp.  I am currently using a Luxkit A3300 preamp.  Other components are:
Naim Uniti Serve streamer
Musical Paradise MP-D2 DAC
Otomon Lab custom build 300B amp
Spatial Audio X5 speakers

I am looking for a tube linestage between $2000-$3000.  From several years ago, I read good things about the following:

Cary SLP98
Modwright SWL 9.0 SE
Supratek Chardonnay
And more recent ones with good reviews:

Coincident Statement LineStage
Linear Tube Audio MZ2/MZ3
Don Sachs Model 2 preamp
I have three questions:

1) Is there other models I should consider?  
2) are those in the first group still good options since they are older models?  3) anyone have experience in them and can do some comparisons?

@jjss49 i spent the whole day research on it since I saw the ad.  I think it is a fact that it is not as popular as brands like Don Sachs, LTA and Modwright.  It has good reviews from a smaller community.  Not saying it is bad, but I am just not sure if it is better than other options on my list.  Also, another reason I didn’t jump on it is because it is an older model using a different set of tubes compared to the latest.  The seller doesn’t have original packaging.  I am concern it get damage from shipping.  All these adds up.  Sometimes buying things is like that, based on gut feel.  
@smodtactical  I have been using tube preamp for a long time.  Sticking with tube will have less risk of surprise, I think.
The MZ2 is a fantastic pre amp/ headphone amp, i`m using one with a Pass XA25. Sound is real and lifelike honestly hard to want for more. I will be selling the MZ2 shortly as i ordered a Supratek DHT pre amp.
