I own Bliss Hifi, a high-end audio boutique and this T+A Elektroakustik SDV 3100 HV Streaming DAC Preamp is being listed as a dealer demo from my showroom. It is in near mint condition and perfect working order, presenting largely like new. As a dealer, I can issue the remaining warranty of three years on the unit on to its next owner.

It comes with Remote control, stock power cables, manual, wifi accessories. Original box included.

In my ownership, the SDV 3100 HV is by far the best preamp and DAC I have ever had the pleasure of experiencing in my room. It may be the best product T+A has ever made across any component, accessory, or speaker they’ve ever produced. It delivers truly natural harmonics and tonality, exhibits exceptional resolution and speed, all while demonstrating a respectable amount of grace. The time has come for me to sell this as a dealer demo and refresh the unit I have on the floor.

Check my stellar feedback and buy with confidence. This listing includes palletized freight shipping and insurance across the CONUS at no cost. I prefer fee-free payments, which include ACH bank payments, PayPal F&F, Venmo Gift, cashier’s check, and personal check (has to clear prior to shipping), but I can accept credit card payments through my QuickBooks invoicing system.

Happy to answer any questions. Thanks for your consideration.

More about the unit:
The SDV 3100 HV represents T+A’s most ambitious digital source component, combining reference-grade streaming DAC, comprehensive preamplification, and headphone amplification in a single chassis employing separate high-performance converters capable of processing true DSD 1024 and 32-bit/768kHz PCM. Built from pure aluminum with absolutely no ferro-magnetic materials and featuring five compartments separated by aluminum dividing walls, the SDV 3100 HV employs Double-Differential-Quadruple-Converter architecture with four 32-bit Sigma-Delta DACs per channel in true dual-mono design, with current/voltage stages following the D/A converters built entirely discrete without operational amplifiers and utilizing T+A’s revolutionary HV (High Voltage) technology that drives transistor stages at voltages normally associated with valve amplifiers for inherently more linear character. The comprehensive connectivity includes one AES/EBU input, two coaxial S/P-DIF, two BNC, two optical TOS-Link (all supporting 32-192kHz/16-24bit), two USB DAC device-mode inputs supporting asynchronous data transfer up to 768kSps PCM and DSD 1024, two USB master-mode ports for mass storage, two HDMI inputs plus one HDMI output with ARC, Bluetooth, and both XLR and RCA analog inputs, while the integrated preamplifier section utilizes the volume control module from the P 3000 HV and the Class A headphone amplifier exploits HV technology for outstanding sound quality, all controlled via the F 3100 remote or T+A MusicNavigator app with four selectable synchronous upsampling algorithms (FIR short, FIR long, Bezier/IIR, Bezier).

Reviewers describe the SDV 3100 HV as perhaps the most comprehensively equipped digital converter and preamplifier on the market today, with Hi-Fi+ praising its impeccable connectivity and comprehensive specification that exceeds even ambitious standards, while The Absolute Sound declares it represents the pinnacle of digital’s ascent from early CD players to today’s highly sophisticated machines, noting there is no better way to exploit today’s vast array of options for accessing digital music than via this T+A component. German publication Stereo awarded 100 points for sound quality, proclaiming “Die beste Quelle, die uns je begegnet ist, stammt aus Deutschland” (The best source we’ve ever encountered comes from Germany), describing T+A as having created a new world in development, finish, and especially sound quality that exceeds very high expectations given the price, while Future Audiophile’s Paul Wilson ranks it as one of the best DACs available anywhere regardless of price—a world-class component with engineering excellence where absolutely nothing was left to chance by T+A’s team of twelve full-time engineers and two physicists. Described as towering in every sense, representing both a massive engineering achievement and fabulously refined way to unite physical media and file-based/streaming music that’s as future-proofed as one might hope for, the SDV 3100 HV exemplifies the astonishing transformation of digital source components into highly sophisticated multi-format platforms, with the added benefit that HV series products maintain excellent resale value, typically selling quickly on the secondary market due to their reputation for decades of problem-free use and owners’ tendency to hold onto them.
