I've read a few of the reviews online and I must disagree with them! These speakers do NOT need a super-tweeter, and I'd say for 95% of my listening a sub-woofer isn't needed either. They definitely go lower than my previous Sachiko double-back-loaded horns did. The photo is representation to show what my Beauhorns look like because I don't have a camera. thetubeguy1954 Fri, 06 Jan 2017 19:25:16 -0500 Musical Paradise MP-D2 DAC http://www.diyaudio.com/forums/gallery/showphoto.php/photo/14528 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/14528" target="_blank"><img title="MP-D2_DAC_B_.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/MP-D2_DAC_B_.jpg" alt="MP-D2_DAC_B_.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: USB and Clock Isolation --- USB line interference form dirty computer side always affect DAC performance. MP-D2 introduces innovative isolation technology to completely isolate between the dirty PC side and the clean DAC side, so it gives you the most pure USB PC-HIFI performance you have never experienced before. Power Supply --- 150W toroidal transformer for analog section. Additional 80W toroidal transformer for digital sections. They provide more than 6 times power pool redundancy to support to most critical surge current requirement. They are magnet shielded in the compartment underneath the motherboard. The most advanced lowest noise LDO regulators are employed. In addition, more than 50000uf of total filtering caps are on-board. All of these deliver the highest standard of power performance once found only in leading edge lab equipment.

Analog Output Stage - Tubes and Caps --- MP-D2 output stage only employs vacuum tubes. No solid state component, zero feedback and fully balanced circuitry. Tube rectification circuit delivers more analog sounding. The unique design of the MP-D2 supports multiple series of signal and rectifier tubes. It is also the first one in the world offering user changeable output stage coupling capacitors. No soldering is required! You owns the freedom to select the tubes and caps. You have never felt anything like it. Chassis --- The full chassis is built with aluminum alloy. Even the legs, knobs, tube protection rings and buttons are made with solid aluminum alloy. The simplicity of front panel design allows you get used to it in minutes. How it sound? Well after listening I agree with Musical Paradise's description. It's extremely dynamic, vivid and detailed sounding. Excellent bass weight and extension. The mid-range &amp;amp; highs are smooth, liquid and airy with a deep and wide sound-stage. But the harmonics, pitch, tone and timbre are to die for.

I had previously been using either the Bluenote solid state Stibbert or the tubed GoldNote Stibbert CDP since 2003 ---{GoldNote is who Bluenote became after Bluenote records threatened to sue}--- I couldn't find CDP I thought was more analogue sounding than the Stibbert! However on 7/2016, after just one listen to this YBA CD4 it replaced the tubed GoldNote Stibbert ver. 5. I loved so much! Truth be told, the YBA Genesis CD4 is the most analogue CDP I've ever heard! This player uses a top loading Sanyo HD850 CD transport and incorporates the YBA's patented Blue Diode design. YBA has a Blue Diode that shines on the CD and according to YBA allows the laser to read the bits with less errors and jitter. All I can say is it's so darn good I sometimes think I'm listening to a TT, except then I realize there's no pops or ticks and I'm dragged back to reality... thetubeguy1954 Wed, 22 Jun 2016 17:29:46 -0400 Dayton PS220-8 Full-range Drivers http://www.diyaudio.com/forums/gallery/showphoto.php/photo/9152 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/9152" target="_blank"><img title="Dayton_PS220-8.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1494/thumbs/Dayton_PS220-8.jpg" alt="Dayton_PS220-8.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: At $275 a pair these relatively inexpensive Dayton PS220-8 8&amp;quot; full-range drivers ---{once they've had their cones treated with a somewhat expensive cone treatment}--- are absolutely phenomenal sounding!

Ultra thin wire: 0.001” (one-thousands of an inch) thick. Very thin wire is important for: · minimizing skin effect (no harshness in the upper midrange and treble) · minimizing time-domain errors (necessary for the clean, well defined bass, and perfect imaging) · in realistic cable dimensions, allows the use of the STEALTH proprietary distributed LITZ geometry. Proprietary non-resonant cable geometry: aka Stealth multicore distributed LITZ: · Individually insulated strands (to eliminate direct electrical contact, i.e. galvanic interaction between strands – otherwise the multiple bare strands behave like a single thicker wire) · Non-inductive bifilar winding - the advantage of the STEALTH multicore geometry. · Electrical resonance control: the advantage of the STEALTH distributed LITZ geometry. · Mechanical resonance control: dielectric and jacketing mechanical properties: optimized density and damping. Too much damping usually sterilizes and deadens the sound, while too little damping is even worse because of excessive “ringing” (unwanted uncontrolled resonances). Characteristic impedance control: optimized relationships among capacitance, inductance and DC resistance: the &amp;#346;AKRA characteristic impedance and its resonant behavior (“Q” at RF frequencies) are different from any machine-made cable. Ultra low energy storage dielectric: Stealth para-vacuum (Helium gas) + porous - i.e. foam-like Teflon. The Helium dielectric, combined with the multicore geometry, are the MAIN technical advantages of the &amp;#346;akra, compare to the Indra. Porous Teflon has the lowest dielectric constant of all solid and semi-solid materials. Low dielectric constant = low energy storage = low distortion = fast sound. Helium gas dielectric properties is much better than even porous Teflon, better than air, and better than realistic (commercial) vacuum. Proprietary Stealth connectors: custom and highly advanced; very low overall mass, solid silver contacts, machined ultra-modified PTFE (Teflon®) dielectric, Kevlar composite frame, Carbon Fiber/Titanium shells. Advanced termination technique (high pressure crimping = cold weld) – a direct contact = seamless transition between the wire and the contact – no intermediate agent (solder) involved; thetubeguy1954 Fri, 19 Feb 2010 12:32:23 -0500 Audio Room (Front View) http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4967 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4967" target="_blank"><img title="My_System.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/My_System.jpg" alt="My_System.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: This old photo is looking at my then system from the prime listening position on the center of the couch that you can see in photo: Audio Room (Side View) My audio system, which is my pride &amp; joy, represents the culmination of many years that's passed since 1967 when I was 13 and just learning of how &amp; what to listen for. It all began back when I first heard the Beatles on the radio. I begged my parents to buy me a stereo, but they wouldn't do it. So I assembled my first audio system by gutting the insides of various audio consoles that were left out by the side of the road once a month on special collection days, when literally anything could be left on the side of the road next to your regular garbage pails in Connecticut. I think it's kind of funny actually to remember how it all started off. I attached a wagon to my bike, grabbed some of my dad's tools and off I went! I traveled up down all the streets and eventually within a couple of months I had a stereo that consisted of two separate tube mono-blocks amps of different make and probably different power too, a tubed preamp/tuner &amp; TT that were all gutted from the various consoles on the side of the road. But the best part was the night two friends and myself biked to the local high school and stole (remember we were stupid kids) a pair of large metal EV, coaxial, horns that were used for their football games! Dang you should have heard that system kick butt! Later on as a grew up and I obtained jobs I started saving my hard earned cash as I listened to audio salesmen and started purchasing new solid state pieces by Harman Kardon, GAS, as well as the Infinity FET and the Mark Levinson JC-1 preamps! However in time my ears missed the truth those tubes told. So I eventually purchased an Aronov 960I integrated ultra-linear amp and the magic was back! But one day I heard an SET amp at a Central Florida Audio Society get-together and I was smitten! That was when I went out and purchased (completely on a credit card) the Mastersound Reference 845 amp/integrated amp just about 15 years ago now and it's been audio nirvana ever since! My system now consists of the same 135 LB, 40W/ch, Mastersound Reference 845, integrated SET amp, a YBA Genesis CD-4 CDP/Transport, a tubed Musical Paradise MP-D2 DAC that in addition to rolling tubes, allows you to roll the output coupling caps and a beautiful pair of Beauhorn Virtuoso speakers. thetubeguy1954 Thu, 18 Feb 2010 17:17:28 -0500 Audio Room 3 http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4968 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4968" target="_blank"><img title="My_System.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/My_System.jpg" alt="My_System.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: This is looking at my system from the listening postion on the couch you see in Audio Room 1.

It's 135LB, 40w/ch, Italian, SET amp/integrated. I've replaced the stock 12AU7s with Mazda &quot;chrome-plate&quot; 6189 tubes, the stock 5687s with Bendix 6900s and the stock 845s with Psvane WE845 tubes. These WE845 tubes are absolutely amazing!!! They have the capability to convince you you’re actually listening to live, unamplified acoustic instruments and singers rather than a reproduction of them. If your audio system is up to the task and doesn’t hold these WE845 tubes back, they’ll conjure up an astonishing, almost magical sense of live music from virtually every recording you’ll play. Now understand I’m NOT claiming they’ll make a poorly recorded CD sound like a well-recorded one, but what they will do is make it sound better than it ever did before. I’m also NOT claiming they’ll make a studio session sound like a live performance. If it’s a studio recording they’ll make you believe you were in the studio while the music was being recorded and with a live recording the WE845s will transport you to venue where the live recording was made. I believe the best way to judge an audio product is how easily it makes you forget you’re listening to a reproduction of music rather than to music itself. With the WE845 tubes that was very easy to do every time.. After months of critical listening I am still impressed every time I play my system. I know these WE845 tubes aren’t perfect, nothing is, but I’m at a loss to fault them. Over the entire frequency range and with every genre of music I played. There isn’t one aspect of the sound where these WE845 tubes exhibited less than state-of-the-art realism. Their tone color, inner-detail, excellent macro-dynamics &amp; micro-dynamics, the treble is wonderfully extended. The midrange is warm and full-bodied. While the bass has great bottom-end extension and pitch definition and the list of sonic praises could go on and on. In the end perhaps the best thing I can say is these tubes is this: I had a $5000, incredibly musical sounding, prototype tube preamp installed in my system to evaluate and as good as it was and it was very, very good ---{in fact I haven't heard a better preamp, yet}--- that preamp didn’t make as much of a sonic improvement in my system as adding these WE845 tubes did! All hail the new King of the 845 triodes. thetubeguy1954 Thu, 18 Feb 2010 17:17:27 -0500 Mastersound Reference 845 http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4965 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4965" target="_blank"><img title="Mastersound_Reference_845.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/Mastersound_Reference_845.jpg" alt="Mastersound_Reference_845.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: I love this 135LB, 40w/ch, SET amp!

I'm even luckier because it opens to the kitchen, which in turn opens to the dining room. From Audio Room 1 &amp; 2 you can get an idea of how close I sit to the speakers. Which is about 8ft away. thetubeguy1954 Thu, 18 Feb 2010 17:17:26 -0500 Audio Room 1 http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4957 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4957" target="_blank"><img title="Audio_Room_1.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1494/thumbs/Audio_Room_1.jpg" alt="Audio_Room_1.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: I'm lucky, to have a dedicated audio room.

From this POV you're looking slightly to left at the speakers. I should also mention that because this is an older photo the Sachikos have been replaced with Beauhorn Virtuoso speakers and the GoldNote CDP/transport has been replaced with the YBA Genesis CD-4 CDP/transport used solely as a transport with a Musical Paradise MP-D2 DAC! I'll be taking a new photo of my system just as soon as I can borrow someone's digital camera. thetubeguy1954 Thu, 18 Feb 2010 17:17:26 -0500 Audio Room 2 http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4959 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4959" target="_blank"><img title="Audio_Room_3.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/Audio_Room_3.jpg" alt="Audio_Room_3.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: This is still looking into the audio room from the kitchen. The difference is now you're looking slightly to left at the speakers. From this view you can see the Sachikos are tilted backwards &amp; slightly toed-in. thetubeguy1954 Thu, 18 Feb 2010 17:17:26 -0500 Audio Room 2 http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4960 <a href="http://www.diyaudio.com/forums/gallery/showphoto.php/photo/4960" target="_blank"><img title="Audio_Room_3.jpg" border="0" src="http://origin.dastatic.com/forums/gallery/data/1556/thumbs/Audio_Room_3.jpg" alt="Audio_Room_3.jpg" /></a><br /><br />by: thetubeguy1954<br /><br />Description: This is still looking into the audio room from the kitchen.
