Audio Research SP3-a1
For $3,000 you can get a used Herron VTSP-1a which will blow away the SP-3a.  And most $200 phono stages better the early ARC preamps by a long shot.

BTW, I find bi-polar transistors acceptable as long as they are medicated.

@geoffkait You forgot the law about recycling tube vacuum.No mention about cleaning the vacuum.My personal taste leans toward the use of natural vacuum instead of synthetic vacuum.  (I own a tanker car filled with liquified vacuum on a rail siding...

@almarg Agreed.  The Herron would be better matched to a preamp with a higher input impedance.  Keith Herron would be a good source to determine whether changing tubes in a VTPH-2a would overcome a lower input impedance pre.

@I listen to Herron Audio equipment and wonder why they are not priced in the $30,000+ range. 
Dynavector cartridges, old and new
@chakster Thought I'd mention that cart in the context of your thread.  I have heard some DVs that are quite good and some others that are...   But that just proves that even in a single model of cart there can be variations in performance.  Such ...

@chakster And the upgrade cycle will be never-ending.  Spending a bit more up front will end future money spend on continuing the mediocre performance of cheap electronics.  Using a Herron VTPH-2a will certainly make the AT150MLX sing up to its po...

@lewm "Raul has." LOL!!

Get a Herron Audio VTPH-2a and never have to worry about phono stage performance.  It is as good as it gets and can handle high-output and low-output cartridges with equal aginity.  And the price for such a stellar performer is competitive with ev...

@chakster There's a Dynavector Karak Nova 13D in the cartridge section of the 'gon for sale listings. 
If You Were A Swine Looking To Choose Between 3 Preamps...
Swine - you don't mention price or budget.  A used Allnic will probably cost more than a new Herron Audio VTSP-360 and will likely NOT outperform the Herron. 
Jelco TK-850L review
I can find no info on VTA adjustment.  Does this arm have some kind of VTA-on-the-fly adjustability or is it another arm that has frustrating manual stop-everything-and-guess VTA adjustment?  
What is the typical resistance across the various terminals of a MC phono cartridge?
Pretty much EVERY MC cartridge provides this information in their specs.  I recall values ranging from 5 ohms to 40 ohms.  But I'm probably erring.

@avanti1960 I'm looking hard at it.   
Soundsmith Optimized Contour Contact Line Stylus for Rebuild
After serious consideration and consultation with those who actually work on cartridges, I have settled on having Soundsmith install a boron cantilever with a line contact stylus on the Clavis DC I sent there a few weeks ago.
