JRF also has these grooves in their heads and I think they also cut them to
other heads that they relap if the customer requests it. Not at the studio
but can check when there next time.

>> Horch House Press Release:
>>
>> Austria-based Horch House is excited to announce the initiation of
>> ‘PROJECT R2R’: the development of the world’s only brand new reel-to-reel
>> tape deck.
>>
>> Launched in 2012, the Horch House brand has already developed an

>> reel-to-reel tape, vinyl records and in various digital formats.  Now, the

>> where it belongs.
>>
>> As is typical of Horch House, the company will be working closely with
>> some of the industry’s foremost experts in order to deliver the most
>> accomplished outcome possible.
>>
>> In developing their much-admired processes for creating astoundingly high
>> quality copies of original analogue master tapes, Horch House’s expert team

>> in input from some of the world’s leading specialists (think of folks whose

>> you get a sense of the level of know-how involved).
>>
>> This same high level of input will be applied to PROJECT R2R. The aim?
>> “To achieve the best sound quality, bar none,” says Horch House’s joint
>> owner and project leader, Volker Lange, whose excitement about the project
>> is palpable. “My passion for audiophile tape machines goes way, way back,”
>> he explains. “This will be the realisation of a lifelong ambition. And it’s
>> an absolute honour and privilege to be working with a team of this
>> calibre”.
>>
>> In fact the team is already hard at work and hopes to be in a position to
>> show a prototype of the new deck at Munich’s High-End Show this coming May.
