Components Toggle details

    • Speakers: Audio Note AN-E/SPe HE
    Apple finish (satin). On Audio Note stands.
    • Amplifier: Thomas Mayer 45 SE Amplifier
    Two-chassis SET stereo amplifier with separate power supply. 1.5 watts per channel using 45 output tubes and 3.5 wpc using 2A3s.  I'm using old stock RCA 6A6s as a driver tube. Here is a ranked list of the output tubes I have tried so far.
     
    1. NOS globe shape Cunningham 45s (CX-345)
    2. Sophia Electric 300B 2.5v (a drop-in replacement for 2A3s)
    3. NOS RCA globe shape 45s
    4. National Union ST shape 45s
    5. EML solid plate 45s
    6. Sovtek 2A3

    • Preamplifier: Audio Note M6 Phono
    2014 edition of the M6 Phono.

    Phonosection valves:
    3 x JW Western Electric 396a (early 1950s).  These are a big upgrade over the stock GE 5670s.

    Linestage valve:
    1 x Mullard 12au7 1958 long plate.  A really nice upgrade over the pretty great Philips tube that came stock.  I also have an Amperex 7316 and a Sylvania but I prefer the Mullard.

    PSU valves:
    This set is from Audio Note UK and is for the M8 Phono Signature model.

    2 x ECL82 Telefunken

    2 x 5651 RCA

    2 x 6X5 Tung Sol

    1 x Philips E182CC

     

    • Turntable: Reed Muse 3C
    White finish. 

    I've experimented with both drive systems and I'm using the friction drive rather than the belt drive. 

    I've removed the rubber from the feet and placed the table on Stein Signature Super Naturals and then directly on thick maple plank that I use as a rack for my components.

    I've replaced the stock power supply with a linear power supply.

    • Tone Arm/Phono Cable: Cardas 34 AWG Clear
    • Tonearm: Airtangent 1b
    -- I've tried and owned a number of top pivoting tonearms, including those from Reed and Schröder, but I prefer the AT by a wide margin.
    • Cartridge: London Decca Reference
    I love the immediacy and front-row presentation of this cartridge.
    Many people say that you need to keep your records perfectly clean with this cart but experience tells me that it's the stylus, more than the lps, that needs to be kept clean.  The Mr. Clean Magic Eraser does a great job in this respect.
    • CD Transport: CEC TL5
    Belt-drive transport.
    • DAC: Audio Note UK DAC 0.1x
    Silver
    • Distributed subwoofer system: AudioKinesis Swarm Subwoofer System
    4 walnut subs; 2 amplifiers.

    I've added a high-pass filter between the preamp and my main amp.  The main speakers are 3dB down at 60Hz. 
    • Interconnects, Speaker Cables, Power cords: an assortment
    Crimson R.M Music Link
    Oyaide
    Power Cords: Volex 17504
    Some pro audio stuff.

    I used to spend a lot of money on wire but don't anymore
    • Power Treatment: Akiko Audio Corelli
    -
    • Grounding: Entreq Silver Tellus
    With four Siltech Zero Ohm Link grounding wires. (9 AWG)
    • Room Treatment: Stein Music Harmonizer System
    6 Harmonizers (all of them have been upgraded to the "Signature" versions). 

    Though I have 5 Blue Diamonds and 9 Black Stones, I'm not currently using any of them. I find that the Harmonizers, on their own, sound most natural with my speakers and room.
    • Room Treatment: Stein Music E-Pads
    on the windows
    • Record and stylus treatment: Stein Music DE3 LP Conditioner
    just when you thought vinyl couldn't sound any better...
    • Record and stylus treatment: Keith Monks, The Archivist. etc.
    Liquid for RCM: AUDIO INTELLIGENT - PREMIUM ONE-STEP FORMULA #6. 

    Stylus cleaning: Mr. Clean Magic Eraser. 

    LP cleaning: Compressed air machine or the Nagaoka CL-1000 Rolling Record Cleaner.

High-pass filter between the preamp and the main amp.  The main speakers are now down 3dB at 60Hz (9dB at 30Hz etc.).  The device is passive and uses a small Audio Note UK capacitor.  
This takes a lot of strain off the main amplifier.  60Hz and below is largely covered by the subwoofer system.

Thanks. Well stated and on point regarding the benefits from the Corelli, and especially the "no drawbacks" point.

I've always struggled with AC in my condo and have borrowed many expensive  power conditioners and power regenerators to try and deal with it.  In every case the cure was worse than the disease.  The Akiko Audio Corelli simply plugs into an extra outlet and none of your gear plugs into it.  The results are amazing.  Everything becomes more natural, more effortless, and more three-dimensional.  And best of all, there are no drawbacks.

Gorgeous front wall! What are your impressions of the Akiko Audio Corelli?

My cartridge can't track that track even with the volume off so it isn't a vibration thing.

Hi bigamp,
Thank you for the compliment.
That's a good question.  I'll have a look at my cabling and see if I can move the table more toward the centre of the rack.  The only time that I have noticed a problem is on a track on "Sea Change" by Beck.  The stylus can't hold the groove near the end of the song.  I don't think this is because of vibration caused by the speaker but I could be wrong.  As an experiment, I'll temporarily move the table out in front of the preamp (on the floor - well away from both speakers) and try and play that track.  The floor beneath the hardwood is 8" of poured concrete so there shouldn't be any movement there.

Hi Exlibris.  Beautiful system and room.  I've been following your comments about the system's progress over the years.  Congrats on your great results.  I'm by no means an expert on vinyl, but I do wonder if having your TT placed "in front of" your speaker introduces any vibration into the mix?

I made a video of the room for some room acoustics people and I've posted it here.  The video shows the Audio Note M6 Phono with the cover removed (I've been tube rolling) and the CEC TL5 CD transport out of the system -- as it sits on top of the M6.

I switched back to the idler/friction drive on the Reed Muse 3C table.

I immediately noticed that the bass tightened up and there was better definition in the bottom end.  I could more easily follow bass lines.  Because the bass was less dominant and bloated, more information from other frequencies came through.  It was as if the soundfield was 'cleaned' and each image had more room to breathe.  Pitch definition and was much better - especially noticeable on piano.  All of these improvements led to a much more natural sense of space and timing. 

So, was anything lost by going away from the belt?  Well, the belt is more 'romantic' sounding.  The pace is more languid and notes hang around and take longer to decay.  The midrange is warmer and the overall soundscape is darker.  With the idler everything is simply more there and matter-of-fact -- there is less editorializing. 

It's nice to have the choice between the two but for now I'll be staying with the idler wheels.

Why did I prefer the belt to the idler before but now I prefer the idler to the belt?  The two idler wheels were in the wrong position the first time.  The two wheels are of slightly different diameter and the bigger one has to go on the left motor.

I've removed the Minus K 150BM-1 Vibration Isolation Platform.  Now that I live in a condo with an 8" concrete floor, even jumping up and down beside the turntable has no effect on stylus tracking.

Added a CEC TL5 belt-drive CD transport and I've ordered a budget DAC to go with it.  These will replace my ancient CD player that I'm tired of repairing.
