Recommended Posts

Item Condition: DIY as new 10/10
Shipping Options: Pickup available but audition is not available.,Shipping is included in price.
Suburb or Town: Langwarrin 3910
State: Victoria
Payment Method: PayPal, bank transfer, cash on pickup.
Reason for selling: Two many preamps

Further information: Smart looking in vivid red and even better sounding SRPP tube preamp. Built on a Hammond Wood cheek chassis with external PS. A 24V wall wart (provided) powers the PS which joins to the preamp via a heavy cord. Tubes are Gold Lion Gold pin E88CC. This original design was re-tweaked by the designer to work even better with this specific tube. Two selectable inputs from small front Switch one set of output RCAs. Drives into heavy loads with ease and powers my Holton amps well.

 

4oz solid brass gold plated knob on Alps blue velvet pot. WBT silver solder throughout and Russian Military PIO caps on the output. Silver plated wire wrap wire use for internal hookup.  Final HT cap is Russian (subbed) 4uf PIO. Both HT and heater voltage is DC and triple Pi filtered. Tubes have Dragon Ring dampeners. PS is choked with a Hammond 5H choke and 400uf  of 400V filter caps. 

 

A very natural sounding super clean preamp with a fast and nibble touch. Dead quiet operation.  Through my system passes bass down to 30hz which is as low as my system will go. From bass to treble there is an absolute flat response with no hint of uneven response. Fine detail is presented with ease making listening very enjoyable.

Are you taking maximum output voltage swing to drive your power amp?

It will have more than enough gain to dive and even over-drive your tube power amp.

      The Matrix Element X can drive a set of headphones, active speakers or an amp and passive  speakers. It does DLNA streaming, MQA and functions as a Roon Endpoint or Airplay renderer. I used it in a second system mainly with Roon over WIFI network and Spotify via Airplay. I have tried the coax, optical  and usb inputs and they all work fine. I haven't tried the IIS as I don't have anything compatible.

      Item Condition: Very good Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Rosebery State: NSW Payment Method: PayPal, cash on pickup Reason for selling: Downsized to 2 channel set-up Further information:
       
      Selling my excellent Marantz processor. As I’m in an apartment I scaled back to two channels and am using my valve pre instead.
       
      Excellent DAC and power supply section means it acts as a great stereo preamp.
       
      In great condition but there are some markings on the front.
       
      Note: Remote included but doesn’t function. Will need to repaired/replaced.

      Item Condition: Excellent Shipping Options: Shipping is included in price. Suburb or Town: Templestowe State: VIC Payment Method: PayPal or Cash Reason for selling: More tubes than I can use Further information:
       
      I bought three sets of Philips NOS tubes from a fellow SNAer a few weeks ago to see which ones suit my preamp best. They all have relative strengths.
      This set has good bass and is much better than the current production Mullard, but they are not as nice as the other two sets. So I decide to sell these 3 tubes. I have used them for about 10 hours.
      From the faint code, I gather that they are made in Hendon Works, Alberton, Australia in the 50's.

      Selling my Bryston BP26 Pre-Amplifier and MPS-2 Power supply combo both in Black Colour. The units were both purchased from Carlton Audio Visual in 2016. There is 16 years warranty still remaining on both units. The overall condition of both the Pre-Amp and Power supply are in very good condition.  I do not have the original packaging but can organise shipping interstate.  The BP26 does not come with a remote as this was a factory option at the time, but a Logitech remote can be used.  
       
      Current RRP new is $10000, price is negotiable if you have any questions please do not hesitate to contact me.
       
       
      No-Compromise Preamp
      Bryston's BP-26 preamplifier offers a significant step forward in capturing the subtleties, nuances, and emotions of recorded music. Designed inside and out to reflect the improvements in the entire Bryston line, the BP-26 is a perfect match to Bryston's new SST series of amplifiers. All aspects of the signal flow are greatly improved, with lower noise and distortion figures, and higher overload levels.
      "Great-Sounding and Forward-Looking"
      The BP-26 won an Editors' Choice Award 2020 from The Absolute Sound magazine, which noted, "The BP26 sounds musical and engaging with fabulous rhythmic drive and momentum. It is tonally neutral with an open quality that does not veer toward edgy or forced. It imparts a sure-footed foundation with good bass extension and control. The Bryston’s musicality is more along the lines of a winning, agile tunefulness, than musicality derived from a beguiling, silky lusciousness."
      The April 2008 issue of the British magazine What Hi-Fi Sound and Vision lists their top choices and best buys in quality hi-fi components for 2008. The Bryston BP-26 not only made the list, but also earned the highest possible rating of Five Stars.
      "Better Than Anything We've Heard at This Price"
      A joint review of the BP-26 preamp and the 2B SST power amp in the September 2008 issue of What Hi-Fi Sound and Vision observes that the pair "blends transparency with insight and punch better than anything we've heard at this price."
      The March 2005 issue of The Inner Ear Report calls the Bryston BP-26 "a component worthy of the term high-end." According to the review, "Bryston's production work is first rate and the components used in all their designs are of top quality."
      The PB26 was honored by winning the "Best Preamplifier" Trade Award for 2010 from SVI magazine. SVI stands for 'Sound Vision Install,' and SVI is England's leading home electronics trade publication.
      Dual Chassis Approach
      Bryston's unique, no-compromise dual-chassis approach isolates the power supply of the BP-26 in a separate chassis for ultra-quiet operation. Please note that the BP-26 requires the MPS-2 power supply, which is sold separately.
      Clean, Lifelike Musical Signal
      The BP-26 has been engineered to deliver the cleanest, most lifelike musical signal. Intermodulation distortion has been reduced to less than .0015% from 20 Hz to 20 kHz. The noise floor has been significantly improved, reducing background hash to far below audibility. Input to input crosstalk is essentially nonexistent to eliminate signal bleed-through from one source to another.
      The BP-26 is housed in a steel cabinet for shielding to reduce electromagnetic interference effects. Buffered inputs provide for lower distortion and improved linearity from source components. A ground plane has been incorporated in this new design to further reduce crosstalk and noise throughout the internal circuitry. The power transformer is mounted externally to eliminate power-supply noise interference.
      The Bryston gives you lots of connectivity. It offers five stereo RCA inputs, two stereo RCA outputs, two XLR inputs, one XLR output, a stereo tape loop, and a headphone output.
      Hand Assembled Components
      Premium components and meticulous construction techniques contribute to the extremely high performance level offered by the BP-26. Components plug directly into glass-epoxy circuit boards, eliminating variations in signal travel and wire interaction.
      Signal switching and audio connections utilize heavy gold plating to provide long-term trouble-free connections. Gold plated balanced and unbalanced input and output connectors are standard. A 12-volt AC / DC screw terminal connector on the rear of the power supply provides for a convenient remote start feature available on all Bryston amplifiers.
      Each and every BP-26 preamplifier is assembled by hand and burned in for 100 hours to ensure performance for many years to come. It is backed by a 20-year warranty from Bryston, which is unrivaled in the industry.
      The optional Bryston BR2 remote control allows remote operation of the BP26.
