KW225i Hybrid Integrated Amplifier
The KWH 225i represents the culmination of years of SS and tube preamp and amplifier design. Our preferred approach has always been that of a hybrid system. Our first preamp was tube and our first amp was SS. Our sources have always been tube and until recently, all of our amps were all Solid State. The KWI 200 SS integrated amp was a big success for us, offering excellent performance and integration. Many customers however, found that it too sounded better when fed via tube preamp. So we decided to take things to the next level. We combined solid state output stage of our Reference KWA 150SE amp, with the controls and integration of the KWI 200. We then replaced the SS preamp circuit with a Class A tube design and increased the power to 225W. The result is the KWH 225i. We think you will like it!
LS36.5 Linestage
The LS 36.5 represents ModWrightÂ’s finest tube linestage performance, offering true balanced outputs and XLR inputs. It follows our SE tube linestage, the SWL 9.0SE, offering a higher level of performance, aesthetics and options. Remote volume control are standard, as is phase switching, also via remote! The LS 36.5 takes sonic performance to the next level, offering a broader and deeper soundstage and a weightier presentation, compared to the 9.0SE. Refinements in power supply design, voltage regulation, and driver circuit design all serve to raise the bar. Refinements in grounding, transformer coupling and shielding also yield a 2 x lower noise floor than its SE predecessor! Those wishing to take the performance of the LS 36.5 to the next level again, have the option of adding the PS 36.5 dual-mono, all-tube external power supply. This PS 36.5 features a complete dual-mono topology, including dual tube rectifiers and tube voltage regulation circuitry
KWA150 Signature Edition
Power Amplifier The KWA 150 provides the strengths of both tube and solid state products: 3-D sound-staging, holographic imaging, and a beautiful midrange of tubes, combined with sparkling highs, low distortion, bass resolution, and control of solid state. The heart of the KWA 150 Amplifier is a single voltage gain stage called the Solid State Music Stage. The circuit was developed by Alan Kimmel, creator of the exceptional vacuum tube Mu stage. Features include: high-low bias switch, stereo/bridge-mono switch and true balanced floating inputs, accepting balanced and unbalanced inputs. The design incorporates a regulated power supply for the input stage, Cardas best connectors and oversized heat sinks. The first watts operate in pure Class A. The KWA 150 uses no global feedback, is direct-coupled, fully differential, dual-mono, bridgeable, and designed and built in the USA. Summary of key elements of upgrade from standard KWA150: Upgraded model of Lundahl input transformer for improved speed and dynamics. Circuit design revisions to input circuits that lower distortion and improve dyanmics and resolution. Cryo-treated, solid core ultra-pure input wiring and 12GA stranded audio-grade output signal wire to binding posts. Revised capacitor bank (current storage design) that increases total storage (capacitance) and also lowers power supply impedance, which translates to faster current delivery to the output stage. This all translates to the following in terms of sonics: A more open and resolving overall presentation. Tighter and faster bass and transients. Improved speed and dynamics, whilst still retaining tube-like midrange qualities.
SWL9.0 AnniversaryPreamplifier
Celebrating our 17th year in business, the SWL 9.0 Anniversary Edition tube linestage is a tribute to our first product, the SWL 9.0SE.
The namesake of Dan Wrights son, Spencer Wright, born 9.0lb at birth, the SWL 9.0SE was released thirteen years ago with great success as a high performance and high value tube linestage.
The SWL 9.0 Anniversary Edition retains the 5687 driver tube and many of its features, but is a complete redesign from the original.
Unlike the original, the Anniversary Edition includes a modern headphone amplifier and optional phono stage.
The SWL 9.0 Anniversary Edition represents MWIs entry level product with exceptionally high level of performance and value.
LS100 Tube Preamplifier
LS100 tube single-ended preamp from ModWright .The design goal of the LS 100 was to pick up where the 9.0SE, the first Modwright product to be produced over seven years ago, to the next level. The goals were improved sonics, aesthetics and functionality. Single-ended design with 10 function remote control, (2) 6SN7 (Driver) and (1) 5AR4/GZ34 rectifier. Single gain/buffer stage, phase inverting, five standard inputs, one Monitor input and tape output, one Home Theater Bypass (HT/BP) input and three main sets of RCA outs. Remote Control Functions Include: Power Two remote trigger outputs Selectable balance control, may be bypassed for cleaner signal path Volume control Mute Input select Monitor input select Preamp Functions Include: Upgrade slot for Optional in-board DAC or Phono stage Built in headphone amp fed via tube driver stage Home Theater Bypass All pushbutton control, no toggle switches The LS 100 is built in the same size enclosure as the KWA 100 amplifier and has the same lines and aesthetics, including backlit logo. Taller enclosure allows for greater range of rectifier tubes to fit inside. Sonically, the LS 100 offers a greater control, ease, musicality and resolution, all perfectly balanced for the ideal musical experience. Frequency response is flat from 20Hz to well beyond 100Khz. Soundstage is extremely wide and detail and microdynamics co-exist with a tube warmth and natural musical presentation that must be experienced!
