Seems like you made the right choice. The SPL is really nice too but I think the LA4 was the right call if you are focused on instrument detail and soundstage, the Benchmark was probably the best bet.
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!
