Pre amps cost vs. value ... what I discovered last month.

Greetings all.

I’m a mastering engineer. www.magicgardenmastering.com . We use Acoustic Zen balanced cabling, highly modified Cary 211 FE tube amps, Bricasti M1 SE DAs and Joachim Gerhard’s Allegra speakers. TORUS balanced power comes 220 from the street. The room is excellent, and you would love to hear it.

For 15 years the pre amp/router was a Crane Song Avocet. I paid around $1800 for it.

Recently decided to try a couple of audiophile products in the pre amp stage and was shocked and saddened how bad they were. Yes, the studio designed Avocet has a relay click for each 1db step, and yes it has a rack mounted 2U body with a corded remote, but it’s clear folks are really getting taken to the cleaners on pre amps. The older and highly regarded Boulder 1010 (used price $5500), was just terrible, truly terrible. The new and fully broken in BAT vk-43SE (demo price $7500) was much better, but still had a cloudy tone as compared to the class A Avocet. Not sure if that’s the cap or the transformer, but it made everything less clear and more generic, more distant from the music.

That’s all. Happy listening.

Was just listening to the Moody Blues "In Search of the Lost Chord". My word, what a lousy sounding album. I wonder if there was a mastering engineer involved in its creation.
I loved this album, and have two or three version one being the MFSL, and yes there is no good copy of it very compressed, as this DR shows all green means good, only track 11 (The Word) has good DR.
And this site has never let me down on which one to get, click on the one with the highest and most green and you have the cat no of it and go search ebay for a used copy.

@brianlucey Interesting findings. I've been mildly curious about how pro gear compares. I have no experience with BAT, but the two times I heard all Boulder electronics, it was very disappointing. They have extremely impressive build quality, but they were unequivocally NOT musical IMO. 

As others have suggested, it would be interesting to hear your comparisons to Ayre, Levinson, Pass Labs, etc

One other thought. Perhaps there is poor synergy due to impedance matching or other technical factors when mixing pro and home gear.

Yes @spenrock poor matching is always possible yet the Boulder sounds to me as it sounds to others I trust who I’ve talked to since. Again, great company, so well done, just not right in any way that I know of. And I’m not saying pro gear across the board is better or worse, not going there ... just talking about these 3 units in the pre amp category only.  Levinson is dry, analytical, well done, just not very engaging.  At this point I'm looking to completely rebuild and upgrade cost no object the crossovers in the speakers (fairly complex) and stay with the old Avocet.

1. Have you tried driving the amps directly from the Bricasti by using its volume control instead of the Avocet?

2. Have you tried some SS amps on the Allegras?  Their non flat impedance affects the frequency response of your tube amps and they're not an easy load either.
