Need a new all round high end vocal mic

...for a all round high end studio microphone. I make vocal house / pop music. I was thinking a Neumann u87ai, u47 or m147 or m149. I also used a Sontronics Saturn and Aria once recently and got great results but thinking Neumann is the way forward. I have been using a Rode NT1A with my UAD...

Slate Digital VRS8 Thunderbolt Interface - Now Available

...waste any time. 1st and 2nd violins where Neumann U67's, violas U87's, cellos AKG 414 with C12 capsules and basses where U47 tubes. Room, which is where 90% of your sound should come from, where C12's and Royer 121's. At the same time I've used ML2's for violins and room, and ML 1's for the cellos...

Product Description

The U 47 used the M 7 capsule originally developed for the CMV 3 microphone ("Neumann bottle"). Its PVC membranes unfortunately tended to dry out with age, however, and in 1960 the M 7 was superseded by the K 49, a capsule with similar acoustical design but membranes made of age-resistant biaxially oriented PET film. The U 47's circuitry was based on the Telefunken VF 14 M vacuum tube, the discontinuation of the U 47 was caused primarily by the decision by Telefunken to halt production of the VF 14. In some ways the functional successor to the U 47 was the U 67. Custom tubes equivalent to the VF14 have been manufactured specifically for the U 47, by Telefunken and others. Beginning in 1962, Neumann offered a fully functional Nuvistor, small signal receiving tube replacement kit for the VF14 and required minor circuit modification. The U 47 is well known for its clear sound, with a distinct emphasis in its upper-midrange frequency response. It has been used in countless famous recordings. The Beatles' producer George Martin used the U 47 extensively in the group's recordings and claimed it was his favorite microphone. The U 48 was identical to the U 47 except for the available polar pattern combinations (cardioid and figure of eight instead of cardioid and omnidirectional). According to Neumann: The Microphone Company. by Anselm Roessler, the U 48 was not introduced by Neumann until 1957. However, according to representatives at Georg Neumann GmbH, examples of the U48 existed as early as 1950. The U 47 fet, a solid-state microphone with yet a third capsule, the K 47, had a headgrille identical to that of the original U 47 but with solid-state circuitry; it was produced by Neumann during the years 1969-1986. It was intended to recapture the sound of the original U 47, but enjoyed only limited success. However, the U 47fet became well known among recording engineers as a bass drum mic. If used on the outside of the bass drum (or bass drum head if there was no hole cut in the bass drum head), and in conjunction with a primary bass drum microphone, (which would usually be placed on the inside, or close to the inside of a bass drum or a bass drum head), mixed together would make a complete bass drum sound. The U 47fet also gained great popularity among double-bass players in the jazz world.
