View Classified Spatial Audio Lab M4 Sapphire Open Baffle Speakers - White This is a like-new, mint condition pair of Spatial Audio Lab's new M4 Sapphire speaker. Finish is the semi-gloss, textured white. These were ordered in May 2021 and built and shipped in late October 21. Manufactured 10/19/21. These have been used for roughly 400-500 hours as recommended for full burn in and are not currently in use. They are ready to ship or be picked up. These are flawless. If you're considering these, make sure you can leave at least 3 feet behind the front baffles and 18" from the sidewalls to give them room to breathe. More space may be better depending on the size/shape of your room. Plenty of rave reviews out there, but these are nice overviews: Steve Guttenberg - https://www.youtube.com/watch?v=1EqRo9qbWpQ New Record Day - https://www.youtube.com/watch?v=YHv9wBB3bjw Why am I selling? I want to try something different in my space and need to free up funds to experiment. Naturally, local pick-up around Chicagoland is preferred, but I am willing to ship in the continental U.S. as I have all the original packaging. Each speaker panel ships in a protective sleeve with molded foam and in it's own box. The speaker bases ship in a foam-lined third box. Insured UPS Ground shipping in the Midwest is $200, West Coast is estimated at $250, and East Coast is estimated at $225. Please message with any questions.

View Classified Rogue Audio Stereo 100 (ST-100) Tube Power Amp - Free Shipping This is a used, but very good looking Rogue Audio Stereo 100 tube amp. Comes with Tung Sol KT120 power tubes (4) and new production Mullard 12AU7 (2) and 12AX7 (2) signal tubes. The power tubes bias easily and hold bias. Amp interior is clean and there are no issues to mention. Some very minor cosmetic blemishes on the cover that you'll likely never notice and a light scuff on the front panel that is only noticeable from side angles. See photos that emphasize these. The amp cover is pictured without the screws, but they are included and will be in place for transit. Ships in a custom fit box and includes a power cord and manual. This is the second Stereo 100 I've owned. Excellent sounding tube amp that hits hard, with nice bass extension, a wide soundstage, and warm but transparent sound signature. Excellent build quality and made in the USA. This thing is a 60+ lbs. beast with massive power transformers putting out 100 wpc. Has 4-ohm and 8-ohm speaker taps, and balanced and RCA inputs. For my fellow tube rollers, I contacted Rogue about compatibility. The following power tubes can be safely used: KT120 (stock) biased to 40mA (100 wpc) 6550, KT88, and KT90 tubes biased to 35mA (85-90 wpc) KT77 tubes biased to 30mA (70 wpc) I have the following matched sets available if interested: Genalex Gold Lion KT77 matched quad – add $125 (purchased in 2020, maybe 500 hours on them) Mullard (new production) KT88 matched quad – add $140 (purchased in 2021, less than 200 hours on them) Mullard (new production) 12AU7 and 12AX7 pairs, great for a backup set – add $70 (purchased in 2021, less than 200 hours on them) My asking price INCLUDES SHIPPING in the U.S. and is net to me. Local pickup around Chicagoland will be discounted the estimated shipping expense.

View Classified PrimaLuna DiaLogue Premium HP Integrated Stereo Amp and Headphone Amp This is a used, but very good condition PrimaLuna DiaLogue Premium HP integrated amplifier. I’ve owned it for 5 years and have used it with a wide variety of speakers and headphones. This is a great, versatile unit with a ton of power and tube rolling options due to PrimaLuna’s auto-bias design and massive transformers. Headphone amp is seriously unrated and can power any headphone thrown at it. Functions flawlessly. Remote was just replaced by Upscale Audio. Some minor blemishes that need to be noted (also see photos which make them look worse that they are): a small ding on the tube cage, a few paint chips on the right side, some paint flaking around the transformer cover (this is a finishing flaw and not damage by mishandling or misuse; I have never removed the transformer cover, and the tubes pretty much hide this from view). These blemishes are negligible from your listening position. Power output varies based on power tubes and ultralinear or triode mode: 70 wpc with EL34, 73 wpc with KT88, 89 wpc with KT120. Several other types of power tubes can also be used safely up to the massive KT150. The stock PrimaLuna branded EL34 power tubes (8) and 12AU7 (6) signal tubes are included in my asking price. These have low hours on them as I spent my time with it rolling many other tubes, plus PL amps run tubes very easily, so longevity is not an issue. I have the following matched tube sets available if interested: - Genalex Gold Lion KT77 matched octet – add $250 (purchased in 2020, maybe 500 hours on them) - Genalex Gold Lion 12AU7 matched sextet – add $175 (purchased in 2020, maybe 500 hours on them) - Mullard (new production) KT88 matched octet – add $275 (purchased in 2021, less than 200 hours on them) - Mullard (new production) 12AU7 matched sextet – add $100 (purchased in 2021, less than 200 hours on them) - Take all the tubes for $750 extra Ships in original foam and double box and includes the manual, remote, and power cord. My asking price INCLUDES SHIPPING in the continental U.S. and is net to me. Local pickup around Chicagoland will receive a discount. I am also selling my PrimaLuna EVO 100 Tube DAC, which pairs perfectly with this awesome amp. Seller soundapprentice Date 12/07/21 Price 3,100.00 USD Category Amplifiers
