CHANGING FROM AUDIO RESEARCH TO AUDIO NOTE SYSTEM 


Dear All,

I got hooked by the SET sound and am considering selling my Audio Research based system (REF 5 SE preamp and REF150 power) and Wilson SOPHIA 3 speakers. In exchange I would buy a level 3/4 system. M3 phono balanced input pre, P3 Tonnmeister power and AN E AN-E-SPe HE 98db or  AN-E/SPx ALNICO 95 dB speakers. 

However, considering the good quality I already have, I fear being a little downgraded. Wonder what is your opinion. 

My room allows corner placement, and has 30 m2 with 2,4 m height ceiling. 

Best regards,

an interesting experiment for you try, just for fun. A friend had a difficult room setup and had his Sasha Daws in a room that required placement closer to a wall/corner. They were boomy and completely overloaded the room, tonal balance all wonky. We devised a plan and fitted a flexible hose from a shop vacuum securely into the rear firing Wilson port and rerouted the port output to the front. The hose for each speaker was then terminated into a repurposed subwoofer enclosure where he could adjust the bass by adjusting the quantity of dampening fill in the enclosure. It shouldnt have worked well…but he still uses the contraption. People always ask what brand of subwoofer…LOL. Its an easy experiment to see if you can reclaim some floor space without losing the music.

 

This might give you some idea of room gain adjustability that your particular corners will project.

@thastum What monoblock SET amps provide 80WPC? The highest wattage SET I'm aware of use 845 tube which may provide somewhere around 20WPC.

I believe there are 833 amps claiming 150 wpc.  Also, the ultra rare 1610 can probably do 80 wpc.  I tend to prefer the lower wattage, non-transmitter tube SETs, but 211 and 845 amps can be quite nice sounding.

The Wavac Sh 833 mono blocks,

Sidebar 1: Specifications

Description: Direct-heated-triode, single-ended, class-A tube monoblock power amplifier. Tube complement: one each WE437, 6550/KT88, SH-833. "Effective" power: 150W (no distortion percentage specified). Frequency range: 20Hz-100kHz. Input sensitivity: 1V. Input impedance: 100k ohms. Signal/noise ratio: >100dB (no reference level quoted).

As @larryi noted , very likely the 1610 tube is capable of considerable single tube power.

BTW the relatively common and available 805 is a DHT output tube capable of 50 watts pure class A SET.
