Benchmark LA4 vs SPL Elector vs PS Audio StellarGold


Starting a new thread.  Originally I was looking to upgrade my power amp, but based on feedback I am pivoting and looking to upgrade the pre-amplifier.  Here is my current set up:

Current System:

Acoustat 1+1 speakers

Rythmik pair F12SE subwoofers

SPL Crossover (German Brand.  This separates the signal and reduces the demand on the Acoustats.  It helps bring out the mids and highs on the 1+1's

NAD C165BEE pre amplifier 

Technics SL-1500 C with AT 540ML cartridge in a RigB housing (think AT740ML+)

Marantz 8003 SACD (essentially retired with all CD's on digital card)

Eversolo DMP A6 streamer (occasionally use the DAC, but find it is too bright for extended listening

Schitt Bifrost 2/64 R2R DAC

Nakamichi PA 7All Power Amp (Nelson Pass Stasis design) (may update later to mono block units)

All three preamps claim to be relatively neutral with wonderful soundstages. 

The SPL is $2600, matches my SPL crossover, but may have lesser parts.  There is some concern regarding the volume controls.  Actual owners don't seem concerned.  The dealer will take the C165BEE as trade, thus lowering my costs.  Still waiting on trade value. 

The PS Audio Stellar Gold is $4000 with trade value for my preamp of $1000.  The designer of the unit has apparently left for Parasound (?).  Very positive reviews everywhere.

The Benchmark LA4 is $2950 with the trade value TBD.  This unit also has positive reviews everywhere.

I am looking for improved soundstage (depth and width) plus improved individual instrument detail.

I would appreciate your thoughts and any other suggestions.

 

Thanks!

When I purchased the SPL Elector the Benchmark was on my short list. 

 

It came down to the internal build for me along with both units having excellent reviews for neutrality and lack of presence. Having a Krell preamp as well I know what quiet is and the SPL has it in spades. The Benchmark has so much circuitry under the hood while the SPL has a nice design with high voltage rails. 

 

The kicker was the nice meters. I really enjoy watching them jump around sometimes. I use the XLR balanced input to a Pass Labs X350.5. True fully balanced I don't know.

 

By the way the volume pot is Alps and is nice and smooth and extremely well known in the pro realm. The steps are not that large.

I have not heard the SPL, I was considering it at one time. I already had a LA4 and needed another preamp for another system I was building.

In terms of being quiet I think the LA4 is going to be hard to beat. You should compare the measurements to verify. The LA4 runs warm which is usual for a Benchmark component. In terms of sound, it really does not have any. If your other gear sounds good, then the LA4 will let you hear that other gear without decorating the sound. The volume clicks and I like that. It is also the best volume control I have owned. All amps I have tried with is work perfectly, I cannot say the same for another LA4 like preamp, the Topping pre90.

If I was not going to get another LA4 (for variety), I wanted another preamp that had similar attributes of the LA4, and I got it with the Holo Serene preamp. It is a touch warmer than the LA4 and the volume is not as robust as the LA4’s. However, it does sound very similar to the LA4 (almost no sound). It is likely in-between the SPL and the LA4 in terms of sonics. I think the Serene works very nicely with Class A amps.
