Yep agreed, I sent them an e-mail about the mods and heres the meat of their reply:
Here are the details:
Customer needs to supply the unit ~ $2K, unless you can get a deal.
Our mod price only is $2K and includes the following:
Complete re-design of stock analog stage in Transporter. Volume control in unit is still active, as are all firmware, wireless, Ethernet, SP/DIF, optical ins/outs, etc.
Tube stage features internal power supply, based on design technology from our own preamp designs.
Tube-rectified power supply using 5U4/5V4/5AR4 compatible rectifiers. There will be room to use 5UV/5V4 'G' and 'GB' types, for the 300B look or the straight bottle look. Signal tubes and rectifiers will be mostly exposed and easily accessible from the top. The fuse block will also be external, so there will be no need to open the unit up to change fuses or swap tubes. The exposed tubes will also keep the box cool inside. Heat producing SS devices in the circuit will be heat-sinked to the AL chassis, so the case may run warm, but the temperature inside the box will be kept at a normal opearting temperature.
Tube analog stage featuring balanced outs (differential) to XLR outs and SE outputs to RCA jacks.
Tube analog stage designed around 6CG7/6FQ7/6922/7308/6DJ8/6N1-P tube family. Two tubes are used, but only one triode per channel is used in the circuit. The second triode is not used, allowing for 2x the tube life by simply swapping the tube positions.
The balanced outputs are achieved by custom wound output transformers from Electraprint (Jack Iliiano) - www.elecraprint-audio.com.
Voltage output is approximately 2.5V max, in-line with a typical CD source. This is still plenty of gain to drive most amplifiers to full output level, allowing for the unit to be connected directly to the amplifier. Note: It was designed and voiced, being fed into our LS 36.5 tube linestage.
I expect to schedule the first start date within two weeks from Monday, or by Sept. 10th. Turnaround is expected to be approx. 2-weeks and our scheduling of start dates is intended to insure this.
We require a $500 non-refundable deposit to insure a start date, with the remainder due upon completion of work.
